The prerequisites for the mind to inquire the truth of everything –
An open mind that is unattached towards any particular way of thinking and belief to analyze or judge everything. Letting go all kinds of subjective judgment and comparison.
Free from expectation towards everything that everything has to be/not to be in certain ways. Allowing everything to be what they are, even if the mind dislikes and disagrees with it. Being undisturbed by names and forms that the mind dislikes, disagrees with and doesn’t want.
Free from pride and arrogance or low self-esteem (they both are the same thing.)
Free from blind-believing, blind-following, blind-practicing, blind-preaching, blind-sharing.
Free from fear towards ‘religious authority’, ‘superstitions’, ‘criticism’, ‘condemn’, or ‘the truth that is not necessarily the way that the mind believes what it is or how the mind would like it to be’.
Being aware of the mind is ignorant towards the unknown, or many things that are beyond the knowledge of the mind, and is aware of the mind is functioning/perceiving/understanding everything under a particular way of thinking and belief in the mind that influence how the mind perceives, analyzes, judges, feels, acts and reacts towards all the mind perception of names and forms, which is nothing to do with the truth of what things are.
The state of the mind of calmness, quietness and purity, being free from stimulation, incorrect/corrupted thinking, restlessness and impurities.
It’s like the function of a mirror.
The mirror that is cracked/contorted, or is shaky, or is full of dust and dirt, cannot reflect the image of things as it is. The reflection of things is distorted/contorted, or blurred, or not what it is. Even though the reflection/image of things are distorted/contorted, blurred and not what it is, being reflected onto a cracked/contorted, shaky and dirty mirror, it doesn’t change the truth of the things. The truth of things is still what it is, being undetermined, unaffected, undisturbed, or unaltered by the cracked/contorted, shaky and dirty mirror.
Just like a mind that is functioning under the influence of the defilement of ignorance or incorrect and corrupted thinking, or is restless, or is under the influence of egoism and impurities, cannot reflect the truth of things as it is. The perception or understanding of things are incorrect, corrupted, blurred, or not what it is. Even though the perception or understanding of things is incorrect, corrupted, blurred and not what it is, being perceived under a mind that is over-powered by ignorance/incorrect or corrupted thinking, restlessness and impurity, it doesn’t change the truth of things. The truth of things is still what it is, being undetermined, unaffected, undisturbed, or unaltered by the ignorant, corrupted, restless and impure state of the mind.
And thus, all the different forms of yoga practice is to be calming, quieting and purifying the mind, to free the mind from ignorance, egoism, impurities and restlessness, to allow the mind to reflect/see things as they are, being free from the influence of any particular worldly cultural/social/religious/spiritual/national/racial/political/educational/philosophical idea, accumulated knowledge, thinking, belief, value and practice to analyze or judge everything.
Reflect upon the truth of things as it is. Everything is just what they are. Neither good nor bad. Neither right nor wrong. Neither positive nor negative. Neither meaningful nor meaningless. Neither happiness nor unhappiness. Neither spiritual nor non-spiritual. Neither superior nor inferior.
