There’s nothing wrong with reading and memorizing and studying the teachings from the ancient scriptures of Yoga or Buddhism. Just that one needs to know how to unattached towards all the teachings in the scriptures, even if some or all of the teachings might seem to be agreeable or disagreeable to the mind based on what the mind thinks it knows, without blind-agreeing/disagreeing, blind-believing, or blind-following, but be determined to purify the mind to free the mind from egoism and impurities, to allow the mind to perform inquiry/investigation to inquire the truth of all these teachings whether they are true, or not.
At the same time, when the mind is still under the influence of ignorance, egoism and impurities, the mind might generate disagreement or dislike towards some or all of the teachings, and out of the egoistic habit of the mind, it might feel disturbed or resentment towards the teachings that the mind disagrees with or dislikes. The disturbed mind would want to argue or debate or discuss about the truth of this and that, which the mind itself isn’t sure what it is. The mind that ‘knows’, would be in silence, allowing others to ‘understand’ or ‘interpret’ this and that in their own ways/versions.
It’s not so much about whether the teachings in the scriptures are all true, or not. Or whether there’s some misinterpretation coming from the impure mind while studying and analyzing the teachings, or there’s some misleading coming from those who ‘prepared’ the scriptures while putting the teachings into words/texts in a particular language, or there’s some imperfection while describing/translating the teachings into a particular language.
Any kinds of written texts or verbal words in any particular form of language is imperfect. That’s why the truth can only be realized through self-realization under a pure mind, and it can never be described/translated into the form of verbal or written words/texts of any languages. Buddha already stated that the truth can only be attained through self-realization via a pure and quiet mind reflection for the mind reflects upon itself to know thyself, it’s never through reading/studying/analyzing/debating/discussing or getting answers from anyone by asking questions, as one will never know whether all the answers from anyone is true, or not, unless one realizes the truth by itself.
Dhamma cannot be written down in words of any languages, and if the teachings had to be passing down through verbal form and be translated into other languages in verbal or written form, and be kept in the form of texts/words in any particular languages, it’s not perfect. Everyone who sincerely wants to follow the path of yoga or Buddhism, must work diligently on purifying and quieting the restless mind to allow the mind to inquire/reflect the truth of everything, including all the teachings from all the scriptures (any kind of teachings in text form or in verbal form of any particular language.)
And it’s not important at all whether the agreements and disagreements coming from the impure mind towards the teachings are true, or not. But it’s about the mind develops non-attachment towards all the teachings as well as all the impure mind reactions of agreements and disagreements towards everything based on ‘what the mind thinks it knows or understands’, without being disturbed by something that the mind disagrees with or dislikes, without being attached onto something that the mind agrees with or likes, remain equanimous being free from craving and aversion towards the duality of what the mind thinks and believes or understands as ‘right’ and ‘wrong’, or ‘true’ and ‘untrue’, that is upmost important.
Any form of argument, debate and discussion that derived from impure minds are useless as the minds are functioning under the influence of impurities. If the mind is free from impurities, there’s no argument, debate or discussion. Swami Sivananda mentioned repeatedly many times in many of his books – Abandon all forms of argument, debate and discussion. Purify and silent the mind. Meditate and realize. Ajahn Chah mentioned in his teachings – There’s only one book to read – the heart, look within and know thyself. Buddha’s teaching – Do not blind-believing or blind-following, investigate the truth of everything via self-realization through purification of the mind and the annihilation of ignorance and egoism – attachment, identification, the desire of craving and aversion.
The truth is there as it is when the mind is pure and quiet, being free from the influence of duality, being free from ignorance and the by-products of ignorance – egoism, impurities and restlessness of the modification of the mind. The truth is not a belief. The truth is just what things are. The truth is still the truth, that all are impermanent and selfless, including what the impure mind perceives as pleasurable enjoyment or painful suffering, regardless of what the mind thinks it knows or doesn’t know, or whether the mind agrees or disagrees with what it perceives based on what it thinks it understands, or whether the mind thinks itself is perfect or imperfect, or whether the world that the mind perceives through the senses appears to be pleasant or unpleasant, or whether the mind is happy or unhappy.
Those who had never read or come in contact with any scriptures or teachings, can still attain self-realization and be free from ignorance and suffering, when the mind is pure. Being free from ignorance and suffering doesn’t change the truth of impermanence and selflessness in all the names and forms, or doesn’t change all the names and forms to be the way that the impure egoistic minds would like them to be.
