Selflessness, impermanence, cause and effect

The core teachings of yoga and/or buddhism are indeed very simple and straightforward.

Selflessness, impermanence, cause and effect.

The mind will see the truth of selflessness and impermanence governed by cause and effect in all and everything under a purified modification/function of the mind that is opened, that is calm and quiet, that is unattached towards any particular worldly passionate egoistic thinking, belief, ideas, values, desires/aspirations, and practice.

It's the entire prolonged mind purification process under certain disciplines that all minds have to go through in order to free the modification/function of the mind from being conditioned by any kind of worldly passionate egoistic thinking, belief, ideas, values, desires/aspirations, and practice, to render the mind calm and quiet being free from restlessness and impurities, that appears to be quite complicated and challenging, or even discouraging for many minds.

It's like, the mind understands that, and is aware of "This is highly important and needed to be done the sooner the better," but, there are many 'excuses', 'justifications', 'obstructions', 'distractions', 'rebelliousness', 'bitterness', 'hesitations', 'procrastination', or 'pride' arising from within the mind itself that hinder the mind from doing whatever that is needed to be done in now.

The minds that don't know, or the minds that think and believe that they know, but they don't really know, or the minds that refuse to know, and they don't respect while aspire to challenge or go against the truth of selflessness and impermanence governed by the nature's law of cause and effect, will only end up in great disappointment, dissatisfaction, frustration, anger, or meaninglessness, and are peaceless. Meanwhile, out of such disturbed peaceless state of mind, the minds would be generating lots of hurtful damaging actions and reactions unto themselves and others, and into the world.

The minds that know and respect the truth of selflessness and impermanence governed by the nature's law of cause and effect, are resting in unconditional peace, devoid of fear and worry, regardless of whether in action or inaction, regardless of all kinds of selfless impermanent changes governed by the nature's law of cause and effect that are happening ceaselessly in the body and mind, and in the world of ignorance and egoism and the consequences of all that.

Regardless of how strong and powerful, or how good and kind, or how selfish and evil, or how prideful and arrogant is the mind in this present moment now, it will change and pass away.

Inquire the truth of everything.
