 Yogic and ethical practices, as well as analyses of the limitations of goals like pleasure, wealth, status, and heaven provide the conditions for self-knowledge by cultivating mental purity (antaḥkaraṇaśuddhi). Mental purity is the removal of epistemic obstructions to knowing brahman, such as greed, anger, selfishness, violence, jealousy, and distraction. It also includes developing positive qualifications such as ethical attitudinal values of equanimity, acceptance, truthfulness, compassion, and benevolence. Mediation practices provide mental stability and focus. These qualifications hone the mind’s capacity to be a proper container for text-sparked knowledge; though, in theory, if a student is already sufficiently qualified, they need not undergo any such practices.
