Srimad Bhagavatam Canto 03, Chapter 02, Text 16

SB 3.2.16

mam khedayaty etad ajasya janma-
 vidambanam yad vasudeva-gehe
vraje ca vaso ’ri-bhayad iva svayam
 purad vyavatsid yad-ananta-viryah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
When I think of Lord Krsna — how He was born in the prison house of Vasudeva although He is unborn, how He went away from His father’s protection to Vraja and lived there incognito out of fear of the enemy, and how, although unlimitedly powerful, He fled from Mathura in fear — all these bewildering incidents give me distress.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
Because Lord Sri Krsna is the original person from whom everything and everyone has emanated — aham sarvasya prabhavah (Bg. 10.8), janmady asya yatah (Vedanta-sutra 1.1.2) — nothing can be equal to or greater than Him. The Lord is supremely perfect, and whenever He enacts His transcendental pastimes as a son, a rival or an object of enmity, He plays the part so perfectly that even pure devotees like Uddhava are bewildered. For example, Uddhava knew perfectly well that Lord Sri Krsna is eternally existent and can neither die nor disappear for good, yet he lamented for Lord Krsna. All these events are perfect arrangements to give perfection to His supreme glories. It is for enjoyment’s sake. When a father plays with his little son and the father lies down on the floor as if defeated by the son, it is just to give the little son pleasure, and nothing more. Because the Lord is all-powerful, it is possible for Him to adjust opposites such as birth and no birth, power and defeat, fear and fearlessness. A pure devotee knows very well how it is possible for the Lord to adjust opposite things, but he laments for the nondevotees who, not knowing the supreme glories of the Lord, think of Him as imaginary simply because there are so many apparently contradictory statements in the scriptures. Factually there is nothing contradictory; everything is possible when we understand the Lord as the Lord and not as one of us, with all our imperfection.
