A stagnant water which is not flowing, there may be contamination. Therefore the restriction is that you should take bath in this well, you wash your clothings in this well. So small wells, they are restricted for a certain purpose, but in the river, there is no restriction; everything can be done there.
So Bhagavad-gītā, you'll find in the Fifteenth Chapter, the Lord says, vedaiś ca sarvair aham eva vedyaḥ (BG 15.15): The purpose of all scriptures and Vedas is to know Kṛṣṇa, or God. So . . . and the Upaniṣad says, yasmin vijñāte sarvam idaṁ vijñātaṁ bhavati (Muṇḍaka Upaniṣad 1.3). If you simply understand the Supreme Absolute, then you understand everything. So this Kṛṣṇa consciousness means it includes everything. The karmīs activities, fruitive actions; the jñānīs, philosophers', speculation; the yogīs mystic power; and bhaktas, devotees,' worship of the Lord—everything is included.
Just like if you have got a millions of dollar, then ten dollar is there, five dollar is there, twenty dollar is there, everything is there. So if you take to Kṛṣṇa consciousness, then you take all kinds of . . . all the well, all the purpose of different type of well is served in the river of Kṛṣṇa consciousness. That example is said. It includes everything.
Just like Kṛṣṇa consciousness, we are . . . take practical example. We are Kṛṣṇa conscious. Now take any religion and take their highest conclusion—it is there in Kṛṣṇa consciousness. Take for example Buddhism. They say nonviolence. Oh, we are nonviolent. Christianism, love of God. Oh, we are simply meant for loving God.
Christian . . . I mean to say, Muhammadan, servant of God, to render service to the Lord. Oh, we are twenty-four hours engaged in the service of the Lord. Yogīs—samādhi, always in samādhi, absorbed in the thought of the Supreme. We are always absorbed in the thought of Kṛṣṇa.
So take any religion, any process, any well. Oh, this river, Kṛṣṇa consciousness, will overflood everyone. There cannot be any comparison. What is there? How much water is there in the well? In the river, unlimited. Thousands of wells can be merged into the river. This example is given. Yasmin vijñāte sarvam idaṁ vijñātaṁ bhavati (Muṇḍaka Upaniṣad 1.3). If you know Kṛṣṇa, you know everything: you know science, you know mathematics, you know philosophy, you know geography, everything. There is no dearth of knowledge. Don't think that a Kṛṣṇa conscious person, actually he can be a foolish man. No.
