Krishna, the meaning of the word in Sanskrit is all-attractive, He is the Supreme Personality of Godhead, also called as God of gods. In otherwords, Krishna is the Godhead because He is all-attractive. From practical experience we can observe that one is attractive due to (1) wealth, (2) power, (3) fame, (4) beauty, (5) wisdom and (6) renunciation. One who is in possession of all six of these opulences at the same time and who possesses them to an unlimited degree is understood to be the Supreme Personality of Godhead according to Parasara Muni a great Vedic authority.
Humanity has not come across another personality like Lord Krishna with His unparalleled activities. By all historical accounts, Lord Krishna appeared 5,000 years back and played his part as a human being to perfection. Within the prison of His maternal uncle Kamsa, where His father and mother were confined, Krishna appeared outside His mother’s body as the four-handed Vishnu – Narayana. Then He turned Himself into a baby and told His father to carry Him to the house of Nanda Maharaja and his wife Yashoda in Gokula. The Vedic literatures give further histories of his appearances over millions and billions of years. In the Fourth Chapter of Bhagavad-gita, Krishna states that He can remember instructing the lessons of the Bhagavad-gita some millions of years ago to the sun-god, Vivasvan, because he possesses unlimited knowledge, Krishna has a memory that is boundless.
Bhagavad-gita, spoken by the Lord, has been acknowledged the world over for its philosophical depth and divine instructions. The world’s foremost western philosophers have paid rich tributes for the priceless wisdom that it offers to mankind. A discerning person will notice that the instruction contained in the Bhagavad-gita is higher knowledge, not to be found in any other book of knowledge.
Generally people think that by advancing the cause of moral principles and religious rites they will be happy. Others may think that happiness can be achieved by economic development, and yet others think that simply by sense gratification they will be happy. The whole world is very eager to satisfy the dormant propensity of love for others, however, if one simply reposes his dormant loving propensity in Krishna, then his life becomes successful. This is not a fiction but is a fact that can be realized by practical application. One can directly perceive the effects that love for Krishna has on his life.
