In the Śrīmad-Bhāgavatam it is explained that if you begin this chanting, then automatically you'll be purified and you'll be able to offer prayers in purification. That system will automatically help you. So there is no question that you shall hesitate. There is no question of hesitate. And Caitanya Mahāprabhu has therefore recommended,
- harer nāma harer nāma harer nāmaiva kevalam
- kalau nāsty eva nāsty eva nāsty eva gatir anyathā
- (CC Adi 17.21)
Kalau, kalau, in this age, you cannot find a man perfectly purified or this, anyway. That is not possible. Therefore you chant Hare Kṛṣṇa, and that will help you, the process of purification. Therefore this is the only system at the present moment that one can be purified completely simply by chanting. Completely. Complete purification means to be situated in pure spiritual life. That is complete purification. Yaḥ smaret puṇḍarīkākṣaṁ sa bāhyābhyantaraḥ śuciḥ. Śuci means purified. The brāhmaṇa—not this caste brāhmaṇa, but actually, those who are brāhmaṇa, qualified brāhmaṇa—they are called śuci, purified, purified.
