So we are worshiping Govindam, the Supreme Personality of Godhead, the original person. So this sound, govindam adi-puruṣaṁ tam ahaṁ bhajāmi, is reaching Him. He is hearing. You cannot say that He is not hearing. Can you say? No.
Especially in this scientific age, when television, radio messages are broadcast thousands and thousands of miles away, and you can hear, now why can you…? Why Kṛṣṇa cannot hear your prayer, sincere prayer? How can you say? Nobody can deny it.
So, premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayanti (Bs. 5.38). Just like thousands and thousands miles away you can transfer the television picture or your radio sound, similarly, if you can prepare yourself, then you can see always Govinda. It is not difficult. This is stated in Brahma-saṁhitā, premāñjana-cchurita-bhakti-vilocanena. Simply you have to prepare your eyes, your mind in that way. Here is a television box within your heart.
This is the perfection of yoga. It is not you have to purchase one machine, or television set. It is there, and God is also there. You can see, you can hear, you can talk, provided you have got the machine. You repair it, that’s all. The repairing process is Kṛṣṇa consciousness. Otherwise, everything is supplied, complete, complete set of machine you have got within you.
