Prabhupada's lecture Śrīmad-Bhāgavatam 1.5.11 - New Vrindaban, June 10, 1969
Actually, this transcendental name of Kṛṣṇa, or God, can be chanted in liberated stage. Therefore we prescribe, while chanting, there are three stages. The offensive stage, liberated stage, and actually on the platform of love of Godhead stage. That is the perfectional stage by chanting. In the beginning we chant in offensive stage—the ten kinds of offenses. But that does not mean that we shall not chant. Even there are offenses, we shall go on chanting. That chanting will help me to get out of all offenses. Of course, we must take care that we may not commit offenses. Therefore this list of ten kinds of offenses are given. We should try to avoid. And as soon as it is offenseless chanting, then it is liberated stage. That is liberated stage. And after liberated stage, the chanting will be so pleasing because that is on the transcendental platform that actual love of Kṛṣṇa and God will be relished. But the same thing... The chanting... In the offensive stage, the chanting, and the liberated stage is chanting... But in the mature stage... Just like Rūpa Gosvāmī, he used to say that "What shall I chant with one tongue and what shall I hear with two ears? If millions of ears I had, if millions of tongue I had, then I could chant and hear." Because they are in liberated stage.
But we should not be dejected for that purpose. We should continue with perseverance. Utsāhād dhairyāt. Utsāhāt means with enthusiasm, and dhairyāt, dhairyāt means perseverance, patience. Utsāhāt. Niścayāt. Niścayāt means with firm determination: "Yes, I have begun chanting. Maybe there are offenses, but if I continue, Kṛṣṇa will be pleased to place me on the transcendental platform when I shall relish what is this chanting Hare Kṛṣṇa." Just like Viśvanātha Cakravartī has given that the mango in the ripe stage and unripe stage. Unripe stage, it is bitter, but the same mango, when it is fully ripe, it is sweet, the sweetness. We shall have to wait for this stage, and we shall have to be careful that we may not commit offenses. Then we, surely, we shall come. Just like a diseased patient, if he follows the regulations given by the physician and takes the medicine, then surely he'll be cured.
