SB 1.10.25 P Departure of Lord Krsna for Dvaraka
The Lord then appears in His transcendental form without any tinge of material qualities. He descends just to keep the state of His creation in a normal condition. The normal condition is that the Lord has provided each and every planet with all the needs of the native living beings. They can happily live and execute their predestined occupations to attain salvation at the end, following the rules and regulations mentioned in the revealed scriptures. The material world is created to satisfy the whims of the nitya-baddha, or everlasting conditioned souls, just as naughty boys are provided with playing cradles. Otherwise, there was no need of the material world. But when they become intoxicated with the power of material science to exploit the resources unlawfully without the sanction of the Lord, and that also only for sense gratification, there is necessity of the Lord's incarnation to chastise the rebellious and to protect the faithful.
When He descends, He exhibits superhuman acts just to prove His supreme right, and materialists like Ravana, Hiranyakasipu and Kamsa are sufficiently punished. He acts in a manner which no one can imitate. For example, the Lord, when He appeared as Rama, bridged the Indian Ocean. When He appeared as Krsna, from His very childhood He showed superhuman activities by killing Putana, Aghasura, Sakatasura, Kaliya, etc., and then His maternal uncle Kamsa. When He was at Dvaraka He married 16,108 queens, and all of them were blessed with a sufficient number of children. The sum total of His personal family members amounted to about 100,000, popularly known as the Yadu-vamsa. And again, during His lifetime, He managed to vanquish them all. He is famous as the Govardhana-dhari Hari because He lifted at the age of only seven the hill known as Govardhana. The Lord killed many undesirable kings in His time, and as a ksatriya He fought chivalrously. He is famous as the asamaurdhva, unparalleled. No one is equal to or greater than Him.
