In plain words
The coming of the body is for action. Doing action is for a purpose. Action, purpose and duty are man's chief works. When there is no work, I sit thinking of them like this: "The devotees, they are sitting there, they are sitting here, they are suffering." Then I do not feel this pain. So it is said that the sādhana done to turn this mind away is itself sādhana. It is in changing the mind that we gain every kind of Ānanda. This is what they called "Mana eva manuṣyāṇāṃ kāraṇaṃ bandhamokṣayoḥ." This mind itself is the form of Viṣṇu. Manomūlam idaṃ jagat. The whole world is filled with the mind alone. At some time you went to the Himālayas and came back. You went to Badrīnāth, Amarnāth, Kedārnāth, all of them, and came back. But how vast a form the Himālaya is! But after you come home, close your eyes once and try to see the Himālaya. That Himālaya comes and enters into you. We see this heart; it is very small. How did so vast a Himālaya fit into your heart? So the heart is not small. The whole world has become the heart. So do not think the mind is something small. … the mind is the very form of Viṣṇu.
Viṣṇu means what pervades everything. So if we think such a mind, the very form of Viṣṇu, is small, how can it be controlled? It is because we think of it as petty, "It goes there, it goes here," that we fall into these troubles. We must recognise the truth, "I am in the mind, but the mind is not in Me." The whole mind is held within the world. The whole world is within one mind alone. … you must not take it as a separate feeling. When there is selfishness, the mind turns small. When selfishness comes, even such divinity turns into pettiness. We go hoping for something. We go to beg. You are not a beggar. You are Master. You must make yourself the master. You must think, "I belong to God." You must not think, "God belongs to me." These are the two chief threads that ran through the Kṛṣṇa Avatāra. All the Yādavas too, out of Ahaṅkāra, by our Kṛṣṇa … the Pāṇḍavas won. "Our Kṛṣṇa, our brother-in-law, our younger brother, our brother": in many such ways, "He is ours, He is ours," the Yādavas all went on thinking of Kṛṣṇa as their own. So Ahaṅkāra set in. As long as this Ahaṅkāra remains, the principle of the Ātma cannot be understood at all. So all the Yādavas were destroyed. The Gopīs were not like that: "Kṛṣṇa, we are Yours. We are Yours," and they gave themselves up to Kṛṣṇa. Because they thought, "We are Yours," Kṛṣṇa was with them always. So: we are Yours, but You are not ours. When we think, "You are ours," You are apart and we are apart.
