So Bhagavad-gītā, the lessons of Bhagavad-gītā, cannot be changed by the whims of rascals. This is not possible. Aham avyayam. Imaṁ vivasvate yogaṁ proktavān aham avyayam (BG 4.1). Avyayam. This yoga is avyayam, not that with the change of time, the meaning would be changed. That is not possible. The meaning would remain the same thing. The millions of years ago Kṛṣṇa said, man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65). That does not mean that the meaning has changed. "Because it has become old, now I can change." The speaker can say that "When Kṛṣṇa says, man-manā bhava mad-bhaktaḥ, so Kṛṣṇa is dead and gone. Now I am incarnation of Kṛṣṇa. You think of me." This is going on. This rascaldom is going on. "Kṛṣṇa is now dead and gone. Now I am avatāra." Then the answer is: "Then you will be dead and gone, then somebody will come." Just like the meaning of "my head." One child, one boy, was reading "my head," and the teacher is explained, " 'My head' means my head." So the child thought teacher said... When he explained the meaning " 'My head,' it is my head," so the child thought, "The teacher says 'my head.' Therefore 'my head' means teacher's head." (laughter) Another person came: "No, no. It is not teacher head. It is 'my head.' " Then he thought brother's head, then father's head. In this way he became puzzled.
So due to this nonsensical meaning, people are puzzled, that "Whom to surrender? Because Kṛṣṇa I do not see." No. Kṛṣṇa is always existing. So you can... Kṛṣṇa is existing, and to be perceivable by you, Kṛṣṇa has appeared before you. Here is the arcā-mūrti. The arcā-mūrti we are serving. It is not that... Don't think. Arcye viṣṇau śilā-dhīḥ. If you are rascal, they will think that "These people are serving a stone statue." The rascals will think like that, but that is not the fact. Here, practical serving of Kṛṣṇa. The same ācārya has taught that here is Kṛṣṇa. Śrī-vigrahārādhana-nitya-nānā-śṛṅgāra-tan-mandira-mārjanādau **. Śrī-vigraha. This arcā-mūrti, śrī-vigraha, ārādhanam, you should worship. This is the ācārya-panthā. This is the paramparā.
So this worship is going on under this paramparā system. It is not manufactured. Ācāryaṁ mām... What the ācārya says, if you follow, then you become perfect. Tad viddhi praṇipātena paripraśnena sevayā (BG 4.34). If you follow the instruction of ācārya, then you understand perfectly everything. Tad viddhi praṇi... But you have to understand by praṇipātena, by submission, not by challenging. If you challenge, then you will never be able to understand. This whole process is submission. Sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). If you are not prepared to submit, then you will never understand. You will remain in this tamas, tamas. Tamasi mā. But don't remain in tamas. Come to the light.
