In plain words
All the sounds are there inside that tape. If you cut the tape into pieces, will you hear any sound? Or if you put on a magnifying glass and look, will you see those sounds? You will not see them; you will not hear them. But when it is joined to the current in the tape recorder, it sings a song beautifully. In the same way, our heart is a tape. We record all the words of God on it. The tape is filling up with the things we have read. But one thing is not seen. Only when it is joined to the Godhead that is divinity does the tape sing and speak. So we must dedicate our heart and our mind to God. Only then does divinity become visible to us. As long as we stay far from God, the divinity within us will not be understood by us at all. As long as the mind runs out onto physical things, divinity will not be understood at all.
Rāma in the heart, work in the hand
You must turn your mind inward. Carry on your work in the world! Do your duty, work is worship. You need not give it up. But understand the nature of the mind well! Hands in the society and head in the forest, that is rest. ‘Rāma in the heart, work in the hand.’ We must go about our actions in this way. What we do must not be done for show. Our conscience is our satisfaction. The Ātma must be satisfied. The principle of every religion is just this. Every religion has taught only a change of heart. The essence of all religions, the goal of all paths, the essence of all scriptures is a change of heart! We must make the mind blossom. We must make it shine. We must print the divine Name of God on our heart. Uddhava came to test the Bhakti and surrender of the Gopīs. But seeing the change of heart in them, he went back and carried this message to Kṛṣṇa. What did he convey?
