Kṛṣṇa comes, the puruṣottama, to take us back. "Why you are now covered, your shining is stopped? You are morose. You are suffering threefold miserable condition of material existence. Why you are rotting here?" Sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). Kṛṣṇa comes Himself. He is within everyone's heart. He's instructing. He is ready to instruct, but He'll only instruct to such persons who have engaged themselves in devotional service. Kṛṣṇa is there, just like the master is there and many workers are there also. The master speaks to the important persons, not to the ordinary person. Similarly, the master is there in everyone's heart:
- īśvaraḥ sarva-bhūtānāṁ
- hṛd-deśe arjuna tiṣṭhati
- brahmāyan sarva-bhūtāni
- yantrārūḍhāni māyayā
- (BG 18.61)
Whatever we are getting for our sense enjoyment, that is with the sanction, sanction of the puruṣa, the Supreme Person. The paramātmā feature is madhyama puruṣa.
