So this was spoken by Dr. Ghosh, a personal experience. The mantra has got so much power. But not that you purchase the mantra and chant. That will not. You have to make it perfect. There is process, how to become perfect in chanting the mantra. Similarly... It is an ordinary, material mantra. This spiritual mantra... I have already explained. This Hare Kṛṣṇa mantra is spiritual mantra. It is not material. Therefore I've already explained, golokera prema-dhana hari-nāma-saṅkīrtana. It is not ordinary sound vibration, material sound vibration, radio. No. Spiritual. Golokera prema-dhana. So if we actually chant this Hare Kṛṣṇa mantra properly, without any offense, then once chanting is sufficient to make you free from the reaction of all sinful life. Once chanted. There is no question of chanting thousand times. It is said, eka hari-nāme jato pāpa hare, pāpī haya tato pāpa karibāre nare(?). Once chanting of Hare Kṛṣṇa mantra can vanquish so many, so much accumulated reaction of sinful life that a first-class pāpī or a very expert pāpī, he cannot commit so many pāpa. You see. It is so powerful. So if we chant it properly, this chanting, daśa-vidha, ten offenses, without offenses... Nāma-aparādha-śūnyam. Without any nāma-aparādha, if we chant according to the principle, then the mantra will act. Mantra will act in so nicely that the mantra will keep you always in touch with the Supreme Personality of Godhead. That is the power of mantra. Don't think it is a hobby or it is something superfluous. No. Actually, this mantra, Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Himself.
So if you are allowed to keep yourself constantly in company with Kṛṣṇa, then just imagine what is your position. If you keep yourself always near the fire, certainly you shall remain warm; there will be no attack of cold or anything like that. So if we constantly chant Hare Kṛṣṇa mantra, then we are not in this material world. But if we purposely again come to the material world... That independence we have got. But if we chant Hare Kṛṣṇa mantra according to the instructions... Saṅkhyā-pūrvaka-nāma-gāna-natibhiḥ. We have to practice. Because Gosvāmīs, they kept a number, a numerical strength. Haridāsa Ṭhākura kept the biggest. Others, they also kept, but not so big. But according... Because, just like Rūpa Gosvāmī, he had to write so many books, so he was not keeping such a big number as three lakhs. But there was some numerical... Similarly, we must have some numerical strength. And we have minimized. I know that you are coming from a different source, so according to time, according to circumstances... Even there, there is no limit. You can chant more than sixteen-sixteen hundred times. There is no... But practically we see that even chanting sixteen rounds becomes difficult. So don't try to imitate, but do it properly, what is advised by your spiritual master, without any offense. That mantra will save you from the dangers of māyā. That's a fact.
