The path of yoga and Buddhism is about realizing the Truth and respecting the Truth as it is, regardless of whether the Truth is being perceived as something pleasant or unpleasant, agreeable or disagreeable, desirable or undesirable to the worldly impure egoistic minds.
Many minds/people like to talk about 'truthfulness' and see it as an important value of life, but then ironically, most minds/people don't welcome and can't handle certain 'truthfulness' or 'the truth' being something that they don't like and don't want. Many people prefer themselves and everyone else to be playing a game of 'untruthfulness/lies/hypocrisy/pretension/acting' in all forms of relationship that would portray "Everything being the way that they like and want, that would appear to be all good and positive and nothing bad and negative", or they would try to ignore, or deny, or hideaway whatever that they don't like and don't want, such as "Don't tell me about it. I don't want to know anything about it." so that they can have 'the peace and harmony' in their lives, in their relationships with their family, relatives and friends. There's plentiful of untruthfulness/lies/secrets/manipulation in all kinds of human's relationship except in the rare ones that are free from the influence of the ego and egoism. Back-biting exists in many relationships as well, where people pretend to be nice to one another in front of everyone, saying only nice and positive things in front of people in order to maintain 'peace and harmony' in the family, work place, friends circle, personal relationship and the society, but then, many minds/people couldn't avoid back-biting behind people's back to express and/or release their frustration, dissatisfaction and disappointment towards what they don't like and disagree with.
The mind can never avoid some kinds of interaction that involve certain 'untruthfulness/lies/hypocrisy/manipulation' dealing with all kinds of human's relationship.
There's nothing wrong with trying to present many different images of certain 'quality' on different occasions that conform to the many different thinking and beliefs of the many different minds/people that one comes in contact with and interacts with, in order to please everyone, to not offending anyone, to not making anyone feel unhappy, dissatisfy, disappointed or upset, to maintain 'peace and harmony', or to be surviving in a competitive world of names and forms, or to gain love, liking, help, support and comfort from others, but that would be supporting and empowering ignorance and egoism in oneself and others, while yoga practice is mainly to free the mind from ignorance and egoism.
The minds that would be disturbed, offended and upset easily by what the minds don't like and disagree with, or what the minds perceive as unpleasant, disagreeable, bad, wrong, negative or inappropriate, is due to ignorance and egoism. None need to be untruthful, hypocrite, lie, pretend or act while being or interacting with other minds that are free from ignorance and egoism, as these minds won't be disturbed nor offended nor upset by all kinds of name and form that are being perceived by the worldly impure egoistic minds as unpleasant, disagreeable, bad, wrong, negative or inappropriate.
In Buddha or Satguru, or any beings that are free from ignorance and egoism, the mind is undetermined and undisturbed by all the selfless impermanent names and forms, being free from the desire of craving and aversion and expectation towards all and everything to be in certain way. All kinds of suffering/unhappiness/painful sorrow/hurts/depression/loneliness/meaninglessness don't exist in them, as there's neither craving for something pleasant and agreeable nor aversion towards something unpleasant and disagreeable. And hence, there's needless of the existence of any other being or family and friends being there to be loving/liking/supporting/helping/comforting them, although they would allow anyone to be kind and friendly supporting or helping them and/or other beings in many ways, while without encouraging or empowering the ignorance and egoism in the beings, but allowing the beings to also realize selflessness and compassion, being free from all kinds of suffering/unhappiness/painful sorrow/hurts/depression/loneliness/meaninglessness, being undetermined and undisturbed by all the pleasant/unpleasant, agreeable/disagreeable, desirable/undesirable names and forms that the mind perceives through the senses, where the need of gaining love, liking, support, help or comfort from some others is absent, and without egoistic intention to be making and accumulating 'family ties and friendships', they can be 'kind' and 'friendly' towards all and everyone unconditionally without discrimination of 'friends or not friends', 'family or not family' and 'good or bad beings', without the need or craving of gaining love, liking, help, support and comfort from others.
Real peace and harmony is unconditional, derived from the absence of ignorance and egoism, being undisturbed by the mind perception of names and forms through the senses that is subject to impermanence and selflessness. It's being free from all kinds of suffering, restlessness and impurities upon the annihilation of ignorance and egoism. 'Peace and harmony' that is subject to the existence and non-existence of certain quality of names and forms, being determined by certain condition and situation that the mind desires, likes and agrees with, that is achieved and needs to be maintained through certain actions, is not real.
Those who are free from being conditioned by worldly thinking and belief would understand this and are free from the sense of loneliness and meaninglessness. Those who are being conditioned strongly by worldly thinking and belief wouldn't or couldn't understand this and would be perceiving the sense of loneliness and meaninglessness from time to time or most of the time. And hence, the importance of renunciation to free the mind from being conditioned by worldly thinking and belief for sincere yoga practitioners.
One can choose to perform certain actions in the world and be engaging in certain forms of relationship and interactive activity with some others selflessly without any attachment, but not because of one thinks and believes that one has to perform such actions in the world and must be engaging in certain forms of relationship and interactive activity, as one would think and feel bad, wrong, negative, meaningless, unhappy or suffering if one doesn't or couldn't perform such actions in the world, or doesn't engage in certain forms of relationship and interactive activity with some others. That is freedom in yoga or Buddhism.
