In plain words
These ears are like a speaker. By the current called the Ātma, they are all able to hear. The tongue is a mike. If we put this mike in front of us and think we are speaking, then if there is no current in the mike, what I say will not be heard. It is of no use at all. The Ātma alone is the basis of all the senses! Without using the name Ātma, scientists say ‘power’, ‘energy’. This energy is śakti. Even with this energy, if there is no matter, it goes to waste. Just as energy goes to waste without matter, so matter goes to waste without energy. What is God? Matter+energy=GOD. For divine power, both must come together. The mike and our voice must both be there. Here is one more small example of it:
The eyes see. True! But without the light of the sun the eyes cannot see at all. Only on the support of the sun's light can the eyes see that such and such a person is here. People go on thinking that the eyes alone are the basis of it. If there are no eyes, what use is the light? If there is light and no eyes, what use is it? There are many blind people in the world. They cannot see the sun, though it shines so brightly. But how foolish, to say there is no sun just because they cannot see it! He cannot see, but can those who have eyes not see? However great a scholar he may be, he cannot see the world while he sleeps. There is great learning in him. One so great in Jñāna, a man of learning, cannot see the world in sleep. Even a fool with no learning and no knowledge can see the world when he is awake. So for this, neither learning nor power of intellect is needed. The eye of Jñāna in man must open. Only then can the good and the bad of this world be recognised. Because divinity dwells in all men and in all limbs as the very form of rasa, it was said of it, ‘Raso vai saḥ.’
