Krishna, God, the Supreme Personality of Godhead, and his plenary emanations, the Avatars, possess special signs that distinguish them from celestial beings and ordinary human beings.
To prevent anyone from claiming to be Krishna, God, the Supreme Personality of Godhead, or an Avatar, let us know that Krishna alone, and the true Avatar, will be recognized by the special and characteristic signs of their divinity that they bear on their bodies, the palms of their hands, and the soles of their feet.
Signs on the soles of the Lord's feet: A standard, a lightning bolt, a mahout's staff, a fish, a parasol, a lotus flower, and a discus.
Signs on the palms of his hands: Lotus flowers and chariot wheels.
Seven parts of his body shine with a reddish glow: His eyes, the palms of his hands, the soles of his feet, his palate, his lips, and his nails.
Krishna also has a peacock feather adorning his hair and a tuft of white hair on his chest. A large flower necklace hangs around his neck.
Moreover, only He can manifest His gigantic universal form in the material universe, consisting of the entire cosmic manifestation.
If God manifested this universal form, it was precisely to put fools in their place, so that only those who can manifest this gigantic form as Lord Krishna did would be considered Avatars. Materialists may therefore, for their own benefit, focus their thoughts on this colossal form of the Lord, but they should be careful not to be misled by pretenders who claim to be equal to Krishna but prove incapable of acting like Him, or of manifesting this form that contains the entire universe, as well as the characteristic signs of His divinity.
THE AVATAR WHO HAS NONE OF THESE SIGNS AND WHO CANNOT MANIFEST THE UNIVERSAL FORM IS NOT ONE, IT IS AN IMPOSTER.
Lord Krishna speaks to us of the radiance emanating from his body.
Addressing Prince Arjuna, his devotee, the Lord said: My dear Arjuna, this dazzling radiance, this absolute light that you are contemplating, know that it is none other than the radiance emanating from my body. This radiance is none other than myself.
This radiance is an emanation of my spiritual energy.
This radiance extends beyond the realm of my external energy (also called material energy, better known by its material nature). One who dwells in this material world cannot experience this radiance of the Supreme Spiritual Being. Therefore, it is not manifested in the material universe, but only in the spiritual world.
The reasons for the advent of Krishna, God, the Supreme Personality of Godhead, in this material world.
Lord Krishna is the original Person; such is His identity.
When Krishna, God, the Supreme Personality of Godhead, comes into this world, it is certainly to protect His devotees and annihilate the demonic miscreants, but it is also to restore spirituality and propagate true spiritual knowledge, for the benefit of all living beings.
Lord Krishna says, I appear by My internal potency.
