Non devotees cannot understand the contradictions present in the Supreme Lord or His devotees.
“The Supreme Personality of Godhead, being self-sufficient, is full of transcendental bliss (atmarama). He enjoys bliss in two ways–when He appears happy and when He appears distressed. Distinctions and contradictions are impossible in Him because only from Him have they emanated. The Supreme Personality of Godhead is the reservoir of all knowledge, all potency, all strength, opulence and influence. There is no limit to His powers. Since He is full in all transcendental attributes, nothing abominable from the material world can exist in Him. He is transcendental and spiritual, and therefore conceptions of material happiness and distress do not apply to Him.
We should not be astonished to find contradictions in the Supreme Personality of Godhead. Actually there are no contradictions. That is the meaning of His being supreme. Because He is all-powerful, He is not subject to the conditioned soul’s arguments regarding His existence or nonexistence. He is pleased to protect His devotees by killing their enemies. He enjoys both the killing and the protecting.
Such freedom from duality applies not only to the Lord but also to His devotees. In Vrndavana, the damsels of Vrajabhumi enjoy transcendental bliss in the company of the Supreme Personality of Godhead, Krishna, and they feel the same transcendental bliss in separation when Krishna and Balarama leave Vrndavana for Mathura. There is no question of material pains or pleasures for either the Supreme Personality of Godhead or His pure devotees, although they are sometimes superficially said to be distressed or happy. One who is atmarama is blissful in both ways.
Nondevotees cannot understand the contradictions present in the Supreme Lord or His devotees.
Therefore in Bhagavad-gita the Lord says, bhaktya mam abhijanati: the transcendental pastimes can be understood through devotional service; to nondevotees they are inconceivable. Acintyah khalu ye bhava na tams tarkena yojayet: the Supreme Lord and His form, name, pastimes and paraphernalia are inconceivable to nondevotees, and one should not try to understand such realities simply by logical arguments. They will not bring one to the right conclusion about the Absolute Truth.”
