श्रुत्याचार्यप्रसादेन दृढो बोधो यदा भवेत् ।निरस्ताशेषसंसारनिदानः पुरुषस्तदा ॥ ५० ॥
In plain words
When the grace of scripture and of the teacher makes knowledge firm, then the root cause of saṃsāra has been thrown out of that person — the whole of it, with nothing left over.
Close to the Sanskrit
When, by the grace of the śruti and the teacher, knowledge should become firm, then the person is one in whom the entire root-cause of saṃsāra has been cast out.
