Acharya Prashant explains that the biblical instruction to trust in the Lord and not lean on one's own understanding highlights the distinction between impersonal understanding and personal comprehension. He clarifies that true understanding is always impersonal and beyond the mind's limits. When one refers to 'my understanding' or 'my truth,' they are merely discussing mental comprehension, which is limited by personal convenience and ego. The mind can possess knowledge and information, but it cannot achieve true understanding because the mind must be bypassed to reach the absolute. He asserts that 'I understand' is an oxymoron and a statement of arrogance, as the mind cannot contain the infinite. He further elaborates that even the sharpest intellect or deepest thinking does not equate to intelligence or meditation. Just as a galloping horse remains on the ground and cannot fly, the mind's maneuvers cannot grasp the way of God. The mind's best function is to acknowledge its own limitations, and this very acknowledgment is what constitutes faith. Acharya Prashant concludes that while mental comprehension and faith are mutually exclusive, true impersonal understanding and trust are one and the same. The personal ego, which people often mistake for a guide, is not to be trusted in matters of the ultimate.
