Pūtanā entered the county of Gokula, the residential quarter of Nanda Mahārāja, without permission. Dressing herself just like a beautiful woman, she entered the house of Mother Yaśodā. She appeared very beautiful, with raised hips, nicely swollen breasts, earrings, and flowers in her hair. She looked especially beautiful on account of her thin waist. She was glancing at everyone with very attractive looks and smiling face, and all the residents of Vṛndāvana were captivated. The innocent cowherd women thought that she was the goddess of fortune appearing in Vṛndāvana with a lotus flower in her hand. It seemed to them that she had personally come to see Kṛṣṇa, who is her husband. Because of her exquisite beauty, no one checked her movement, and therefore she freely entered the house of Nanda Mahārāja. Pūtanā, the killer of many, many children, found baby Kṛṣṇa lying on a small bed, and she could at once perceive that the baby was hiding His unparalleled potencies, which resembled fire covered by ashes. Pūtanā thought, "This child is so powerful that He can destroy the whole universe immediately."
Pūtanā’s understanding is very significant. The Supreme Personality of Godhead, Kṛṣṇa, is situated in everyone's heart. It is stated in the Bhagavad-gītā that He gives one necessary intelligence, and He also causes one to forget. Pūtanā was immediately aware that the child whom she was observing in the house of Nanda Mahārāja was the Supreme Personality of Godhead Himself. He was lying there as a small baby, but that does not mean He was less powerful. The materialistic theory that God-worship is anthropomorphic is not correct. No living being can become God by undergoing meditation or austerities. God is always God. Kṛṣṇa as a baby is as complete as He is as a full-fledged youth. The Māyāvāda theory holds that the living entity was formerly God but has now become overwhelmed by the influence of māyā. Therefore Māyāvādīs say that presently he is not God but when the influence of māyā is taken away he will again become God. This theory cannot be applied to the minute living entities. The living entities are minute parts and parcels of the Supreme Personality of Godhead; they are minute particles or sparks of the original fire. So these sparks can be covered by the influence of māyā, but the original fire, Kṛṣṇa, cannot. Kṛṣṇa is the Supreme Personality of Godhead, even from the beginning of His appearance in the house of Vasudeva and Devakī.
