Female devotee (1): When in the Bhagavad-gītā it says that the mahā-mantra cleanses the heart and soul, does that mean that when you just, like automatically say the word it says that the mahā-mantra cleanses the heart and soul, does that mean that when you just, like automatically say the words, just the sound, will that cleanse your heart? Or should you try and remember Kṛṣṇa with every word and every sound?
Prabhupāda: No. By simply chanting your heart will be cleansed. Yes. Go on chanting. Therefore we give regulative principle that one must chant at least sixteen rounds.
