kṛṣṇa-padārcana' haya dvāparera dharma

kṛṣṇa'-varṇe karāya loke kṛṣṇārcana-karma

(CC Madhya 20.336)

So in the Dvāpara-yuga, in the next millennium, in the age of passion, Lord Kṛṣṇa was Himself present. And He presented this Bhagavad-gītā. And what did He teach in that Bhagavad-gītā? Sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66).

He personally taught the people of the world that one should be a surrendering soul to the Supreme Lord. That will make him happy.
