By the grace of Kṛṣṇa, if we are sincere and serious, then Kṛṣṇa becomes kind upon us and gives direction: buddhi-yogaṁ dadāmi tam. "I give them buddhi-yogam." Buddhi means intelligence. So here, everyone has got intelligence. At least, he thinks that he is very intelligent. Everyone thinks. Although he's fool number one, he thinks himself as very intelligent. Because intelligence is there. But when the intelligence is used for material fortune, that is unfortune. When intelligence used for developing Kṛṣṇa consciousness, that is fortune.
So we can set up our own fortune or misfortune. The fortune means that we must be serious after hearing about Kṛṣṇa. One must be serious. Kṛṣṇa says, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). So if we are intelligent, we should seriously think over this proposal. Why Kṛṣṇa says: "Give up everything and surrender unto Me"? There is sufficient reason. If one has seriously studied Bhagavad-gītā, there is sufficient reason to surrender unto God, unto Kṛṣṇa. Everywhere.
