- kṛte yad dhyāyato viṣṇuṁ
- tretāyāṁ yajato makhaiḥ
- dvāpare paricaryāyāṁ
- kalau tad dhari-kīrtanāt
- (SB 12.3.52)
In this age the śāstra-vidhi is hari-kīrtana. The more you chant Hare Kṛṣṇa mahā-mantra, the more you become perfect. This is śāstra-vidhi. And Caitanya Mahāprabhu confirmed it. Sādhu-śāstra-guru-vākya. We have to be fixed up, first of all, what is the injunction of the śāstra. Then what the sādhus, those who are devotees, what they are doing. What they are doing, sādhu, śāstra, and guru. And what guru is asking. We have to follow these three principles. Sādhu-guru-śāstra-vākya tīnete koriyā aikya. Who is sādhu? Who is abiding by the injunction of the śāstra. Or guru? Guru means he's also abiding by the injunction of the śāstra. Then he's guru, he's sādhu. He's sādhu. And if one, śāstra vidhim, yaḥ śāstra-vidhim utsṛjya . . . If śāstra-vidhi you give up, then where is the question of guru and sādhu? Na siddhim. He's not siddha. He has not attained the perfection, because he has rejected the principles of śāstra. So he's bogus. We have to test like that, who is guru.
- tasmād guruṁ prapadyeta
- jijñāsuḥ śreya uttamam
- śābde pare ca niṣṇātaṁ
- brahmaṇy upasamāśrayam
- (SB 11.3.21)
The śāstra says who is guru. Tasmād guruṁ prapadyeta. One has to surrender to guru. That is, tad vijñānārthaṁ sa gurum evābhigacchet (MU 1.2.12). One must approach guru. This is vidhiliṅ. Not that it is optional, I may accept the guru or not accept guru. No. Must. Gacchet. Gacchet means he must. It is vidhiliṅ. This verb is used where the purport is "one must." Otherwise, it is not possible.
