In the Gita, in plain and simple language, it is stated that Sri Krishna is the Supreme Personality of Godhead. There is none equal to or greater than Him. He is the root of the impersonal Brahman and Paramatma, the Supersoul in every entity is His plenary portion. He is the fountainhead of everything and everyone is advised to surrender unto His lotus feet.
Krishna is the supreme will in Himself and He exercises His supreme power at His pleasure, which submits to no law, because all law has proceeded from His will and power.
Either pure or impure, or having passed through all conditions of material life, if one can remember the lotus eyed Krishna, he becomes externally and internally clean.
Lord Krishna is the all-powerful, all-pervading Supreme Personality of Godhead and he is the object of the prayers and worship of the demigods. Intelligent persons worship him as He resides in his own spiritual abode. They thus attain the eternal transcendental bliss that is not available for others.
Although the quality of being self-satisfied is eternally present in Krishna, the quality of enjoying pastimes is also eternally present in him. For the Supreme Lord to possess contradictory characteristics in perfect harmony is natural. In one aspect, Krishna has the quality of self-satisfaction and in another aspect, he manifests his opposite quality of enjoying pastimes with others.
What assurance of real happiness is there in all of one's wealth, youthfulness, sons and family members? This life is tottering like a drop of water on a lotus petal. Therefore you should always serve and worship the lotus feet of Lord Krishna.
