Whatever is stated in the Vedas, if you accept, that you don't require to make research how to find out God or how to find out yourself. Everything is there, simply if you accept it. Not blindly. If you want to test it, you can test. Just like this cow dung: in the Vedas it is said it is pure, but if you want to test chemically, you will find it pure. That is Vedic injunction.
Therefore our Vedic injunctions are very supreme evidence, Veda-pramāṇam, śabda-pramāṇam. There are three kinds of evidences. First evidence is direct perception—I see personally. And then historical evidence, and then śabda-pramāṇa. Śabda-pramāṇa means evidence from the Vedas. Out of three kinds of evidences, the śabda-pramāṇas, or the evidences received from the Vedas, that is accepted. So for spiritual advancement especially we have to accept the Veda-pramāṇa, or evidences given in Vedic literature.
So this disciplic succession, as Gosvāmī Hanumān-prasād said, that is essential. That is the Vedic injunction. Tad-vijñānārthaṁ sa gurum eva abhigacchet (MU 1.2.12). This word abhigacchet, it is a form of verb which is used where the sense is "You must! You must!" There is no exception. You cannot say that "I may go to a spiritual master or I may not go. I can study at home." No. You must.
Just like in modern age also, if you actually interested to be recognized as educated, you must get your admission in a recognized school or college and take degree. Then you will . . . if you study at home, you may be very great scholar, and if you say that you have passed M.A. examination, nobody will care for you. Similarly, if you actually want to be advanced in spiritual knowledge, then this is the injunction: tad-vijñānārtham.
Tad-vijñānārtham means . . . vijñāna means science. 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. So after reading your newspaper, you throw it away. It has no . . . after one hour of its publication, it has no value. But this Bhagavad-gītā, it was spoken five thousand years ago, still they are being read with respect and honor. So this kind of literature should be read, not a literature which is printed and you read and glance over and throw it away.
So that is man-manā, thinking of Kṛṣṇa. Man-manā bhava mad-bhaktaḥ. Kṛṣṇa says: "You become My devotee." Man-manā bhava mad-bhaktaḥ mad-yājī (BG 9.34): "You worship Me." Māṁ namaskuru: "Offer your obeisances unto Me." Now, all these item, there is no expenditure, and anyone can do. Even the child can do. What is the difficulty? Factually our children, Kṛṣṇa conscious children, do that. The father, mother offers obeisances, and the child imitates—he also offers obeisance, bows down. So this offering obeisances to Kṛṣṇa will not go in vain. It will have effect.
So it is inexpensive. It is very simple, without any loss. Suppose you have got a picture of Kṛṣṇa and you simply think of the picture, man-manā, and you offer a little lamp, a little incense, and if you don't offer, if you simply offer your respect, what is your loss? Is there any loss? (break) We are all businessmen. We calculate everything in terms of loss and profit. So there is no loss. That's a fact.
