Just like the roaring of a lion drives away the big elephants from the forest—whenever there is roaring of a lion, even the big animals like elephants, they go away—similarly, this vibration of transcendental sound will cleanse the elephants of dirtiness in the mind. We have accumulated dirtiness in our mind after many, many births, and that is a huge garbage. For this transcendental sound is just like the roaring of lion, and it will clear all the garbages accumulated.
śraddhāvāl labhate jñānaṁ
tat-paraḥ saṁyatendriyaḥ
jñānaṁ labdhvā parāṁ śāntim
acireṇādhigacchati
(BG 4.39)
Now Lord Kṛṣṇa says that faithful, those who are faithful, they can acquire transcendental knowledge. This subject matter we have discussed in the last meeting, that without faith we cannot make any progress. In any field of activities we must have faith. For example, I cited the other day, just like we go to your barber shop, and we spread our neck, and the barber has got a sharp razor in his hand. If he likes, he can at once cut my throat; he has got the weapon ready. But because I have got faith he'll not do it—he'll simply shave my beard or moustaches.
So this faith is required in every activity. Without faith we cannot step forward even in our daily life. So if we have got so, so faith in ordinary dealings, don't you think that we must have very good faith when we are making progress in spiritual life?
