धीरो विचारवान्साक्षादादावेव महाधिया ।शास्त्रेण विदुषा शास्त्रं सुजनेन विचारयेत्
In plain words
Śrī Vasiṣṭha said: The steadfast one, possessed of vicāra, should, directly and right from the very outset, with a great understanding, inquire into the śāstra -- by means of the śāstra itself, by means of the wise, by means of the good.
