(Radha Raman, Vrindavan)
"So this is the process of Kṛṣṇa consciousness. We have to hear about Kṛṣṇa, we have to chant about Kṛṣṇa, we have to memorize about Kṛṣṇa, we have to worship Kṛṣṇa. This is our movement. We are worshiping Kṛṣṇa in the temple. We are thinking of Him. We are talking about Him, and we are hearing about Him. So if we live in this way, it does not require any monetary exchange or any high education. Everyone can hear about Kṛṣṇa. Anyone... After hearing, everyone can talk about Kṛṣṇa. And while hearing and talking, he can remember about Kṛṣṇa.
And everyone can worship in the temple. Where is the difficulty? By prosecuting these four principles of Kṛṣṇa consciousness, you become immortal. No austerity. No austerity, no penance, no education, no riches. Simply by following these four principles, you become immortal. So this verse is very important. Āyur harati vai puṁsām udyann astaṁ ca yann asau, tasyarte yat-kṣaṇo nītaḥ (SB 2.3.17). Tasya ṛte, one who is passing time in this way, simply with kṛṣṇa-kathā, chanting also... If you have no time... If you have spare time, don't sit idly. If there is no facility for reading books or talking about Kṛṣṇa, chant Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare. If you have got... Next moment, you can interchange, read something. Always be busy with Kṛṣṇa. Then sun will not be able to kill you. You are going to live forever. This is the process."
