In plain words
Bhakti, Bhakti, Bhakti: Bhakti is that which never knows separation from God. Bhakti is that which is never parted from God. They called Bhakti itself the Gaṅgā. For the people of Bhārata, the Gaṅgā means what is holy, what is pure, what is fruitful; the Gaṅgā is she who has won a reach through the whole world and a holy fame; so Bhakti must be clean, pure and selfless. Karma in keeping with Bhakti: this is the Yamunā. All karmas done to please God are equal to the Yamunā. So all karmas done to please God are the very form of the holy river Yamunā. Selfish karmas, karmas done for one's own ends, are karmas that belong to Yama. This is the Yamunā; that is Yama. Now in the world the two, Bhakti and karma, are seen; but Sarasvatī, flowing unseen beneath, is not seen by us. Sarasvatī is hidden, secret. She is unmanifest. That Jñāna which flows unseen beneath is not seen by us. This Jñāna alone is true Jñāna. That Jñāna is a help in mastering the senses.
I told you last time. Rāma was one who had learned thirty-four arts. Rāvaṇa was one who had learned sixty-four arts. Though he had learned more arts than Rāma, he said, “Rāvaṇo nāma mūrkho'sau”: Rāvaṇa is a fool. Why? Though he had studied so much, it was because he had no mastery of the senses and became a slave to them that Rāvaṇa became a fool. Rāma kept His senses under His own control. So not all who are educated are jñānīs. They may be men of learning. One who has learning and has also gained mastery of the senses is the true jñānī. They have described beautifully, in the form of Bhakti, the characters who recognised this inner meaning and lived by it.
One who is a devotee must not let himself grow weary in any situation at all. Even when he hears again what he has heard before, even when he eats again the food he has eaten before, he must not grow weary of them. Swami may go on telling the same things he has told before. He may make you hear the same things you have heard before. Why? We eat again and fill the same stomach we have filled before. We wash again the same face we have washed before. Why? The food we have eaten is digested. Then we have to eat again. What we have heard, we may forget. To bring back to memory what we have forgotten, we must hear again what we have heard. You must not grow weary of it. A small example.
You began drinking coffee or tea fifteen years ago, twenty years ago. “It is the same coffee and tea we have been drinking all these years, isn't it?”
