So here is . . . Bhagavad-gītā is giving a chance to everyone to become brāhmin or be qualified person who knows Brahman and who is preparing himself for the next birth in the spiritual kingdom. He is called brāhmin. Cātur-varṇyaṁ mayā sṛṣṭam (BG 4.13).
Now, the Lord says, tasya kartāram api māṁ viddhy akartāram avyayam: "Although I have created this system, still, I am not there." "I am not there." Why? Because Kṛṣṇa is neither brāhmin nor śūdra nor kṣatriya or anything, anything of the material world. He is transcendental. When we go to Kṛṣṇa with spiritual body, we also become like Kṛṣṇa in transcendental body. That chance is given here. So just it is our duty, everyone.
Lord Caitanya, He is Kṛṣṇa Himself. He appeared as a devotee of Kṛṣṇa, but He never said that, "I am Kṛṣṇa." But from Vedic references we understand that He is Kṛṣṇa. But the same mission. The Kṛṣṇa's mission and Lord Caitanya's mission is the same. How it is same? Kṛṣṇa, as the Supreme Personality of Godhead, He said that, "You surrender unto Me," and Lord Caitanya said, "You surrender unto Kṛṣṇa." The same thing. Lord Caitanya said . . . what is the philosophy of Lord Caitanya? Lord Caitanya says:
- ārādhyo bhagavān vrajeśa-tanayas tad-dhāma vṛṇdāvanaṁ
- ramya kaścid upāsanā vraja-vadhu-varga-vīrya kalpita
- śrīmad-bhāgavatam amalaṁ purāṇaṁ premā pum-artho mahān
- śrī-caitanya mahāprabhor matam idaṁ tatradaraḥ na paraḥ
- (Caitanya-mañjusā)
