इति गुरुवचनाच्छ्रुतिप्रमाणा -त्परमवगम्य सतत्त्वमात्मयुक्त्या ।प्रशमितकरणः समाहितात्माक्वचिदचलाकृतिरात्मनिष्ठितोऽभूत् ॥ ४८० ॥
In plain words
So, having taken in the truth through his teacher's words, through scripture, and through his own reasoning, the disciple grew utterly still - senses quiet, mind gathered - and there, motionless, he settled completely into the Self.
Close to the Sanskrit
Thus, having understood the Supreme Truth in its real nature through the guru's word, the authority of scripture, and his own reasoning, [the disciple], his senses fully quieted, his mind composed, became at a certain time, of unmoving form, established in the Self.
