9.4.16 sayameva abhisamāgamma, āyatajogamāyasohīe.
abhiṇivvuḍe amāille, āvakahaṃ bhagavaṃ samiāsῑ.
The self-enlightened Lord attained the state of ayata-yoga i.e., self-restraint of mind, speech and body by means of self-purification and became tranquillized. He was upright in his practice of penance. The Lord remained equanimous throughout his ascetic life of self-discipline.
Bhāṣyaṃ Verse 16
The Lord having realized the truth himself, and having perceived and known the āyatayoga, that is, self-restraint of yoga (activities) through self-purification attained the state of self-restraint of mental vocal and physical activities. As a result, he was tranquillized with respect to sensual objects and passions. The penance was practised by the Lord without self-conceit. [1] In this way, the Lord led the ascetic life with equanimity for the whole life.
