Indian reporter: It is there in śāstras.
Prabhupāda: Yes. And if you don't care for the śāstras, if you manufacture your own way, then, as it is stated, na siddhiṁ sāvāpnoti (BG 16.23). You'll never be successful. Na sukhaṁ na parāṁ gatim. Neither happiness nor better life will be next or the supreme goal. These things finished. Yaḥ śāstra-vidhim utsṛjya vartate kāma-kārataḥ (BG 16.23). If you do not take the guidance of the śāstra then all your hope is finished. You can hope, but you'll never be. This is our . . . therefore we follow the śāstras and we teach others to follow śāstras. If you like, you can do. Otherwise, do whatever you like. But you don't manufacture and spoil my life and others. You don't do.
