The word ‘Krishna’ derived from Sanskrit has been interpreted differently by people over the ages. The most literal derivation is ‘all-attractive’.
Lord Krishna is the whole existence in itself — Krishna includes everything. As is often seen in the pictures or stories of Lord Krishna, everything is attracted to him...be it the cows, birds, trees, cowherds, the water of Vrindavana, Gopis, Pandavas, or anyone who has come to meet or know Him.
According to Parasara Muni, a Rigvedic Maharishi and author of many ancient Indian texts, only the one who possesses strength, fame, wealth, knowledge, beauty and renunciation –all the six opulence– at the same time and to an unlimited degree, can be deemed as the Supreme Personality of Godhead.
During his lifetime on earth, Krishna has through his numerous actions proven that He possesses all the six opulence, in supreme capacity.
Strength: Krishna was all-powerful right from his birth. The lord was just 3 months old when Putana, the demon, attempted to kill Him. But with unlimited strength by His side, the divine baby foiled Putana’s attempts, and the demon ended up dying at the Lord's hands.
Fame: From a young age, he demonstrated qualities no human could ever have. During his stay on earth, Krishna slayed powerful demons to protect his devotees. He led Pandavas to victory in the epic battle of Mahabharata. His deeds and miracles has been glorified in numerous texts and poems, all of which brought Krishna boundless fame.
Wealth: According to Srimad Bhagavatam, Krishna owned a staggering 16,108 palaces, all made of pure marble and bedecked with precious jewels. These were home to his near and dear ones. The rooms were adorned with furniture made of ivory and gold. In the history of human society, no human is ever said to have owned riches to this enormity.
Knowledge: Bhagavad Gita is a compilation of the immense sublime knowledge that Lord Krishna imparted to Arjuna before the battle of Mahabharata. The principles stated in the Gita are pertinent even today. Krishna not only possessed sublime knowledge, but also passed it on to his worthy followers.
Beauty: Lord Brahma has described the beauty of Lord Krishna, in many verses of his Brahma-samhita. The beauty of Krishna was so captivating, that one look at Him would make you forget the material world around you.
Renunciation or Vairagya, means to have dispassion or have no attraction to the material world. Krishna possessed supreme, boundless spiritual knowledge, and yet lived a detached and liberated life.
With all the six virtues in abundance, Krishna is truly the Supreme Godhead.
