Some yoga teachers are disturbed, frustrated, irritated, angry and hurt by certain things in the world that their minds perceived as 'bad', 'wrong', 'disagreeable', 'inhumanity', and 'suffering'.
There's nothing wrong with any kind of reaction, as everyone is free to act and react as they are, and most minds would react in such way under the influence of ignorance and egoism. Because of ignorance, they are being ignorant of these reactions are out of ignorance and egoism, but instead, they would think and believe that human beings should be reacting in such way out of loving kindness and compassion, while those who don't react in such way are lack of loving kindness or compassion.
Not all yoga teachers are free from ignorance and egoism. It's normal that there are some yoga teachers are being disturbed by what their minds perceived as 'bad', 'wrong', 'disagreeable', 'inhumanity' and 'suffering' based on certain worldly social/cultural/spiritual/religious/humanity belief, values and practice, and yet, they don't really know what is going on in their minds, while thinking that they and other human beings should be reacting in such way out of loving kindness or compassion. But not really.
Many yoga teachers in the world are like everyone else, taking their own time to evolve, to free their minds from ignorance and egoism at their own pace, while conducting yoga classes for some other people to be learning and practicing yoga with them for whatever reasons, intentions and expectations.
None can 'advise' or 'enlighten' the minds that are still functioning under the influence of ignorance and egoism, including many of the Internationally certified/qualified 'yoga teachers' in the world, who think and believe that they love yoga very much, and claiming that themselves are quiet experienced in practicing and teaching yoga, as they have been practicing and teaching yoga for quite many years already. But all those years of experience in practicing and teaching yoga under Internationally recognized certification and qualification, as well as how much the mind thinks and believes that it loves yoga very much, cannot determine that the mind is free from ignorance and egoism, even when they think and believe that themselves are compassionate loving and kind beings who want to spread love, happiness and peace into the world.
Many people might also be doing many social charity work for the community in the world. It's excellent for people to be reaching out and helping each other in the world. But performing many good actions for many years also doesn't and cannot determine that the mind is free from ignorance and egoism.
All these Internationally certified and qualified 'yoga teachers' are also doing their best to purify and quiet their minds, to free their minds from ignorance, egoism and impurities, to allow their minds to see the truth of things as it is, to realize selflessness, oneness, non-separateness, attributelessness, namelessness and formlessness, to be free from all kinds of disturbs and suffering deriving from ignorance and egoism, to realize unconditional love and peace, being undetermined and undisturbed by all the different qualities of name and form or impermanent pleasant/unpleasant/agreeable/disagreeable/desirable/undesirable life experiences that the selfless mind perceives through the senses, according to what the yoga teachings and practice is about.
If the mind is still functioning under the influence of ignorance and egoism, then most probably the mind is also being ignorant towards the ignorance and egoism existing in itself, and hence, not many 'yoga teachers' are aware of the ignorance and egoism in their minds, even though they practice and teach about awareness or mindfulness, and they are still being passionate towards worldly egoistic affairs and relationships, while being disturbed and determined by the perception of names and forms that the mind perceives through the senses of sights, sounds, smells, tastes, sensations, feelings/emotions, and thoughts process of likes and dislikes, agreements and disagreements, actions and reactions based on their intellectual understanding, knowledge and belief. The mind is still functioning under egoism of attachment, identification, desire of craving and aversion, judgment and expectation, and hence constantly react towards the absence and presence of names and forms/experiences that the mind likes and dislikes, desires and doesn't desire, agrees and disagrees with, and be disturbed and affected physically/mentally/emotionally very much by the absence of something likable/desirable/agreeable and the presence of something dislikable/undesirable/disagreeable, based on certain worldly egoistic social/cultural/spiritual/religious/humanity thinking and belief.
The minds that realized selflessness and compassion, being free from ignorance and egoism, will be aware of all the pleasant and unpleasant, desirable and undesirable, agreeable and disagreeable experiences, events, happenings, conditions and situations, but these minds are not being influenced, affected, disturbed or determined by all those names and forms, as these minds are free from the egoistic attachment, identification, desire of craving and aversion, and expectation. These minds don't deny or ignore all those names and forms, but just being aware of it without attachment and expectation towards the perceived reality has to be or not to be in certain way.
These selfless compassionate minds can be performing selfless actions in the world out of compassion, but there's no attachment, identification or expectation towards the action and the fruit of action. There's no disturbs or suffering in these minds while being aware of the many kinds of suffering that exist in the world and upon coming in contact with names and forms that are unpleasant, undesirable, or disagreeable.
The selfless compassionate minds are free from disturbs and suffering, even though they are aware of there are many things in the world that are being perceived as 'bad', 'wrong', 'disagreeable' and 'inhumanity' that are going against 'righteousness', 'loving kindness' and 'humanity' based on the worldly passionate thinking and belief, where many passionate egoistic minds who love and care for the world passionately, are very much being disturbed by all the things that are 'bad', 'wrong', 'disagreeable' and 'inhumanity', while thinking and believing that themselves are being disturbed is 'the normal reaction and the right thing to do out of loving kindness', while those who don't react the same like them, who remain equanimous in peace, being undisturbed by what is happening in the world would be perceived and recognized by the passionate loving egoistic minds as 'lack of loving kindness', 'wrong', 'inhumanity' and 'abnormal'. There's nothing wrong with that kind of reaction, understanding and thinking, as these minds are not aware of their minds are under the influence of ignorance and egoism, that their minds are being disturbed is due to ignorance and egoism, and out of passionate love and hatred towards what they think is love or hatred deserving.
These minds that are being disturbed and angered by something that they perceived and recognized as 'bad', 'wrong', 'disagreeable', 'inhumanity' and 'suffering', while thinking and believing that they are acting and reacting out of compassionate loving kindness, only indicates that they haven't realized what is compassion. They don't know what is compassion is because they haven't realized selflessness. They haven't realized selflessness is because the mind is still influenced by ignorance, egoism, and impurities, especially passion, attachment, identification, desire of craving and aversion, and expectation. Their minds are acting and reacting out of passionate love, not selfless compassion, as the selfless compassionate minds won't be disturbed by all the 'bad', 'wrong', 'disagreeable', 'inhumanity', or the amount of suffering in many beings in the world that derived from ignorance, egoism and impurities.
These minds are being ignorant towards themselves are disturbed by the passionate love, attachment, identification, desire of craving and aversion, and expectation in their own minds. They feel disturbed, frustrated, irritated, angry and hurt by all the things that they perceived as 'bad', 'wrong', 'disagreeable', 'inhumanity' and 'suffering' in the world, is not coming from all those names and forms, but it's how the minds react towards those names and forms out of ignorance and egoism, and they feel disturbed, frustrated, irritated, angry and hurt because things are not being the way that they think, believe, desire and expect how it should be.
Contemplate on what is peacefulness and how to effectively disseminate peace into the world. Contemplate on the essence of the teachings of yoga about unconditional love and peace that is unconditional and unlimited by the impermanent good or bad qualities of name and form that the mind perceives through the senses.
Upon seeing the truth of what is going on in one's mind, one won't be blaming what the mind perceives as bad and wrong things happening in the world for one's mind reaction of disturb, irritation, frustration, anger, hurt, dissatisfaction, disappointment, unhappiness, grief, painful sorrow, or suffering.
Being aware of something is bad and wrong, and the reaction towards something that is bad and wrong, are two different things. It doesn't have to be related together. But, out of ignorance and egoism, most minds constantly react towards what they are aware of.
How can one promote and spread peace into the world by being disturbed and angry towards what the mind thinks and believes is hindering peace in the world?
The liberated peaceful beings in the past were being at peace while living and performing selfless compassionate actions in the world at different era. It wasn't that those beings were being peaceful because there was nothing bad, wrong, disagreeable, inhumanity or suffering existing in the world during those era. If one can only attain peace and be peaceful when there's nothing bad, wrong, disagreeable, inhumanity or suffering existing in the world, then that isn't what unconditional love and peace is about.
Learn how to be undetermined and undisturbed by all the names and forms. Being undisturbed by all the names and forms doesn't mean that one is unconcerned or denying towards what is happening around. Being undisturbed by others' suffering doesn't mean that one is emotionless and doesn't care about others' suffering. The mind that is free from ignorance and egoism is void of disturbs and suffering that is relating to oneself or others, while might be performing certain actions pointing out the ignorance and corruption in the world and guiding the ignorant minds to see the ignorance and corruption in themselves. There's nothing anyone can do if the mind still doesn't get this or understand this.
