शास्त्रार्थगुरुचेतोभिस्तावत्तावद्विचार्यते ।सर्वदृश्यक्षयाभ्यासाद्यावदासाद्यते पदम्
In plain words
Inquiry is carried on -- through the meaning of the śāstras, through the guru, through one's own mind -- just so long, so long, until, by the practice of wearing away everything seen, the station is reached.
