Spiritual knowledge is also a science. It is not sentiment; it is science. Now, if you like, you can make research work whether this is fact. Just like this cow dung. You may think that, "This is contradiction. In one place it is said that stool of an animal is impure, now here it is again said that cow dung is pure. It is contradiction." So if you like, you can make analysis. But you accept the Vedic injunction as it is—you save so much time, that's all, and immediately become advanced.
Therefore the Veda says that in order to learn that spiritual science, you must approach a person, tad-vijñānārthaṁ sa gurum eva (MU 1.2.12), who is guru. Guru means spiritual master. And who is spiritual master? Who abides by the disciplic succession. He does not change. He does not interpret. He presents things as they are. Just like we are doing. We are presenting Kṛṣṇa as the Supreme Personality of Godhead. Kṛṣṇa says that . . . for spiritual realization, He says, man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65). Kṛṣṇa says that, "Always think of Me." Man-manā. Man-manā means "about Me." Man-manā bhava mad-bhaktaḥ: "You just become My devotee."
So we are teaching our students in that way, how to think of Kṛṣṇa always. Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. (break) . . . walk on the street, and if you chant Hare Kṛṣṇa, you remember Kṛṣṇa. There is no tax for it. There is no loss for it. Suppose if you are free, traveling on the bus or on the train, you have got time.
So instead of reading so many news from the newspaper, if you utilize . . . the newspaper means the repeated thing. Every morning you see something: "Somebody has stolen, somebody has killed, some political leaders have bluffed you," and so many things, the same thing, repetition of the same.
This is also repetition, Hare Kṛṣṇa, but by this repetition, you enlighten your spiritual life. And by that repetition, you simply waste your time, that carvita-carvaṇānām.
