Kaṭha Upaniṣad says, tad-vijñānārthaṁ sa gurum eva abhigacchet: (MU 1.2.12) "If you want to learn that transcendental science, then your first business is to go to a guru." Guru... As God is one, guru is also one. There cannot be different gurus. Nowadays it has become a fashion that "I have got my own guru. You have got your own guru." No. Guru means the representative of God. As God is one, similarly, guru is also one. There cannot be different gurus. Because God is one, how there can be different gurus? The principle of guru is one. (child crying) (aside:) Stop. The original guru is Kṛṣṇa. Yaṁ brahmā varuṇendra-rudra stunvanti divyaiḥ stavaiḥ. Original guru, unto whom Brahmā, yaṁ brahmā varuṇa indra, all the demigods, offering their prayers. Within this universe Brahmā is considered to be the foremost living being, but is he also offering respect to Kṛṣṇa. Śiva-viriñci-nutam (SB 11.5.33). Lord Śiva is also offering respect to Kṛṣṇa. That is the Vedic process.
So Kṛṣṇa is the original guru. Therefore Kṛṣṇa comes to teach these fallen souls. Yadā yadā hi dharmasya glanir bhavati bhārata, tadātmānaṁ sṛjāmy aham (BG 4.7). As guru's business is to protect the subordinate disciples from falldown... Just like I am traveling all over the world twice, thrice, in a year. My duty is to see that my disciples who have accepted me guru, they may not fall down. That is my anxiety. So similarly, Kṛṣṇa, being the original guru, He is also very anxious that "My sons..." We are all sons of Kṛṣṇa, part and parcel of Kṛṣṇa. Mamaivāṁśo jīva-bhūtaḥ (BG 15.7).
- sarva-yoniṣu kaunteya
- sambhavanti mūrtayo yāḥ
- tāsāṁ mahad-yonir brahma
- ahaṁ bīja-pradaḥ pitā
- (BG 14.4)
Kṛṣṇa is not Indian or Hindu. Kṛṣṇa is everything. Everyone is Kṛṣṇa's sons, in any form. Sarva-yoniṣu. Yoni means species. There are 8,400,000 species. So all of them are living entities, and they are part and parcel of Kṛṣṇa. Therefore Kṛṣṇa is very much anxious to see His sons become very happy, just like father wants to see his son very happy.
