In plain words
That is, it was only because all the Pāṇḍavas followed Satya and Dharma that they were blessed and became figures held up as the ideal age after age. That is, all the organs of action and of knowing must follow Satya and Dharma. The Manas and the principle of I too must follow Satya and Dharma. These have been called the five sheaths. This principle of the Ātma is bound by the five sheaths: annamaya, prāṇamaya, manomaya, vijñānamaya and ānandamaya. When these tied threads, the five sheaths, are snapped, the Ātma is easily reached by us. But for the Ātma bound by these to live a free life is impossible, it cannot be done. For the food on the plate to reach the stomach, the mouth and the hand must be put to work. So do good deeds with the hand. Dwell on God with the mouth. The oneness of these two is the principle of Brahman. Merely to think of God with the mouth is not enough. Gramophone records and tape recorders sing. You sing too. Those songs are not songs. That sound must come from the heart. They record it, all that I speak and sing. But if you take out the tape and look, can you see it? If you cut it into pieces, can you hear them! Can you think for that reason that there are no words on that tape? The words and sounds are all on that tape. What must we do to hear it? We must give this tape a connection to the current. Then all the sounds on it can be heard. So make a tape in your heart. Give it a connection to the principle of the Ātma. Then it will sound for you without ceasing, echoing Oṃ, Oṃ, in Ānanda. That is Śabda Brahman.
The sound in the silence is Brahman
Not all the sounds we make are Brahman. We make so many sounds. But the sound in the silence is Brahman. When you sit alone, a kind of sound begins from there. That very sound in the silence is Brahman. Once Rāmakṛṣṇa too said this.
