Why only Lord Krishna ?

Why only Lord Krishna ? Lord Krishna is Supreme Personality of Godhead, no doubt, I believe it, but let’s understand the reason for this : Krishna means all attractive, because unless god is all attractive how he can be god. God has no name, but by his qualities we give him names. If a man is very beautiful, we call him beautiful.  If a man is very intelligent, we call him wise. So the name is given according to the quality. Because god is “all-attractive”, the name can be applied only to him. “All-attractive” includes everything i.e. very beautiful, very wise, very powerful, very famous, very rich, etc. Nobody has the qualities of Lord Krishna, so he is all attractive to everyone. Anyone who prays to Lord Krishna to become rich, powerful, etc will definitely get that.  Even if the evil man prays to Lord Krishna, will be elevated. It is said in the Vedas that the Absolute Truth, or the Supreme  Personality of Godhead, is the reservoir of all pleasure-raso vai sah. Everyone is hankering after someone because he realizes some mellow (taste, pleasure or rasa) in it. Suppose a man is hankering after money because by possessing money he gets a mellow out of it. Krishna is God, the Supreme Personality of Godhead. He is the original and primeval person who is simultaneously expanded everywhere throughout existence and yet is still situated in His eternal abode in His original, transcendental form. He is the all-powerful, all-knowing, and all-merciful being. He is the chief eternal living entity amongst all eternal living entities who are His parts. He is responsible for fulfilling all the desires of the subordinate living entities since time immemorial. Krishna is the original name for God. Krishna has many other names according to the country, culture,and language of different peoples. To the Jews He is Yahweh, to the Christians He is Jehovah, to the Muslims He is Allah. To all He is God, the Supreme Being. Some people think that God is the Brahman, or the formless and eternal manifestation of spiritual energy. They say everything is one and God is therefore everything and everything is therefore God. Devotees of the Lord, called Vaishnavas, accept that Krishna is not only the Brahman but a person. We do not say that Krishna is a person like you or me; on the contrary, He is the supreme Person who is all-powerful and unlimited, whereas we living entities are in every way limited. Krishna is the infinite source of all living beings and we are His eternal infinitesimal parts and parcels. "I am the source of all spiritual and material worlds. Everything emanates from Me. The wise who perfectly know this engage in My devotional service and worship Me with all their hearts." -Bhagavad Gita 10.8 Krishna possesses all good qualities. He is Bhagavan! He possesses all opulent qualities in the infinite degree. He is the most beautiful personality. Since He is the Supreme, He has the supreme form and personality. No one is more beautiful or attractive than He. Krishna attracts everyone. Therefore He is called Krishna, the all-attractive one. Except for the liberated souls, everyone in the material world is attracted by Cupid. But Krishna is so attractive that He not only attracts the liberated souls but He attracts Cupid as well. Krishna is the strongest personality. By His desire alone all the universes are created and destroyed by one portion of a portion of His personal form. He can do anything and everything as He likes. Krishna is also the wealthiest person since all wealth in all worlds everywhere come from Him. Everything animate and inanimate within all creation is owned and controlled by the Lord, who is the actual provider of everything. One who knows this perfectly well never claims anything as his own but uses everything in the service of the Lord. Krishna is the most learned personality for He possesses all knowledge. As He describes in the Bhagavad-gita 7.26, "O Arjuna, as the Supreme Personality of Godhead, I know everything that has happened in the past, all that is happening in the present, and all things that are yet to come. I also know all living entities; but Me no one knows...."  There is nothing in existence outside of Krishna since everything is the energy of Krishna, and therefore there is nothing He cannot know at any time. He is also existing within the hearts of all living entities as the Supersoul and therefore He knows everything which they do or desire. No one is more famous than God. Although people of this world know Him in His different forms and names, everyone is aware of the Lord. Some know about Him by worshiping Him in love and service, and some know Him by negating His existence (the atheists) but everyone knows about God. Someone may be famous for some years on this Earth planet, but he certainly may not be known on other planets or at other historical times. Krishna, God, is known in all planets in all universes throughout all time. And finally, Krishna is the most renounced personality. He is not attached to anything in this world. The only thing which can bind Him is the loving devotional service of His devotees. And even then, if it will expand the devotee's love, He is capable of temporarily renouncing them as well, as He did with the gopis in the famous rasa dance in Vrindavan. Sometimes God appears in this world just to show the people His original, eternal form. Sometimes He appears in other forms according to the requirements of His pastimes. More than 5,000 years ago, Krishna appeared in His original, transcendental form just to please His devotees, annihilate the miscreants, and reestablish the principles of religion. During this time on Earth, the Lord spoke Bhagavad-gita, which is one of the most famous books on this planet. In this literature, He gives the practical method to attain devotional service to His lotus feet. The perfection of life is to attain pure, loving devotional service to the Lord. This is the real goal of all living entities. When one is perfected after a life of pure service, often attained after many, many births and deaths of endeavouring to attain real knowledge, one becomes eligible to go back to the spiritual world, the eternal abode of the Lord, which is far beyond the material realm of birth, death, old age and disease. This verse from the Brahma Samhita describes the nature of Sri Krishna. The Brahma Samhita is Lord Brahma's (the creator of this universe) treatise on Krsna and the spiritual world. ishvaraha parama krishnaha sac-chid-ananda-vigraha anadir adi govindaha sarva-karana-karanam   Krsna who is known as Govinda is the Supreme Godhead. He has an eternal, blissful, spiritual body. He is the origin of all. He has no other origin and He is the prime cause of all causes.   In Nutshell, Krishna says there are 84 Lacs species of life in this material world and we are moving in this vicious circle of birth & death again and again. So, to get rid of this suffering,  Krishna says that the birth as a human being is the perfect gift to get back to the godhead. Krishna says in Kalyuga, the human being can get back to godhead simply by chanting his name.
