Indian lady: Is number important in chanting? It has to be certain number, or you can just chant?
Prabhupāda: Number? Yes, of course, no. Actually, kīrtanīyaḥ sadā hariḥ (CC Adi 17.31). Always to be chanted. But because you cannot do that, therefore you must fix up a number. Saṅkhyā-pūrvaka-nāma-gāna-natibhiḥ. Saṅkhyā-pūrvaka, that "I must chant so many times." That is determination. I have prescribed to my disciples that "You must chant at least sixteen rounds." That is very easy. But there is saṅkhyā. Saṅkhyā-pūrvaka-nāma-gāna-natibhiḥ. The Gosvāmīs, they used to do that. So it is; otherwise, kīrtanīyaḥ sadā hariḥ. The chanting should go on twenty-four hours. Just like Haridāsa Ṭhākura used to do. He was simply chanting. But that is not possible for ordinary man. Therefore they should have a fixed up, that "I must chant so many times." That will fix up the determination. Bhajante māṁ dṛḍha-vratāḥ. There must be some dṛḍha-vratāḥ, that "I must do it." Then the devotion grows very firm. If we become lenient, "All right, I shall do later on..." No, must be done. Dṛḍha-vratāḥ. Mahātmānas tu māṁ pārtha daivīṁ prakṛtim āśritāḥ (BG 9.13). Dṛḍha-vratāḥ. Everything should be determined. Then spiritual progress will be rapid.
