Prabhupāda: So some of the devotees who are now eager to accept the spiritual life very seriously, and they have come to take initiation, this is the first initiation. And after some time when they are accustomed, they... Now they have to promise that they'll give up four sinful activities. Sinful activity... If you indulge in sinful activities there cannot be any spiritual advancement. That is not possible. Just like here there will be fire. If you favorably ignite the fire, it will be blazing. But if you ignite the fire and pour water at the same time, then there will be no blazing fire. Similarly, to advance in spiritual life and at the same time indulge in sinful activities will not help us. The sinful act... The basic principles of sinful activities are mentioned in the śāstra-striya, sūnā, dyūta, pāna. Pāna means intoxication, including chewing pān and drinking tea. Chaya pāna. So one has to give up this pāna. And drinking, smoking, drinking tea, chewing pān should be given up. Pāna. This is one of the pillar of the sinful activities. And meat-eating—meat, fish, eggs—they should be given up. And gambling, dyūta, pāna dyūta (SB 1.17.38), that should be given up. And avaidha stri-saṅgi should be given up.
In this way, if you become cleansed, then... Just like if we get dry wood, then the fire ignites very easily. If we get moist wood, then it takes some time. So voluntarily we should give up these sinful activities. Then spiritual advancement of life will be very quick. And those who are being first-initiated, they must chant at least sixteen rounds. Saṅkhyā-pūrvaka-nāma-gāna-natibhiḥ (Sad-gosvamy-astaka 6). The Gosvāmīs, they showed us the way. Saṅkhyā-pūrvaka. So many rounds we must chant, at least. Haridas Ṭhākura was chanting three hundred thousand times. We cannot do that. That is not possible. So we have made a minimum, sixteen rounds. So those who are being initiated, they must chant at least sixteen rounds. If they can increase, it is better. But not less than that. Saṅkhyā-pūrvaka-nāma-gāna-natibhiḥ.
