The Vedic literature describe that God is not abstract. He has impersonal and personal aspects to his personality which is eternal, blissful and full of knowledge. To elucidate further, if we agree that everything in this creation has a form or say that God is our eternal father, logically it does not make sense the source of all existence can be formless and without any personal qualities.
As a single drop of water has the same qualities as an unlimited drops of water in ocean , so does our individual personality with the limitless qualities of Gods personality.
The Vedic authorities delineates ,one who is possession of all these six opulences “wealth, power, fame,beauty,wisdom, and renunciation" at the same time to unlimited degree is understood to be the Supreme Personality of Godhead. The scriptures describe Krishna to be this God.
Krishna or Krsna, "the all-attractive one," means the original, unique Supreme Person, the source of all that exists. God has many names, and each describes a different aspect of His personality. The name Krishna suggests the most charming and beautiful qualities of the Supreme Person, as He is, and as He appears to His most dear devotees.
