Why Supeme Lord created human life?
“God has specifically created the human form of life to facilitate the liberation of the conditioned soul. Therefore one who abuses human life prepares his path to hell. As stated in the Vedas, puruṣatve cāvistarām ātmā: “In the human form of life there is good possibility of understanding the eternal soul.” The Vedas also state:
tābhyo gām ānayat tā abruvan na vai no ’yam alam iti
tābhyo ’śvam ānayat tā abruvan na vai no ’yam alam iti
tābhyaḥ puruṣam ānayat tā abruvan su-kṛtaṁ bata
The purport of this śruti-mantra is that lower forms of life, such as the cow and horse, are not actually suitable to fulfil the purpose of creation. But human life awards the opportunity to understand one’s eternal relationship with God. Thus, one must control the material senses and fulfil the real purpose of human life. If one takes to Kṛṣṇa consciousness, the Supreme Lord personally feels happiness and gradually reveals Himself to His devotee.
The Lord’s material creation consists of the living entities and dead matter, which the less intelligent try to enjoy. The Lord, however, is not satisfied by those species that blindly strive for sense gratification without understanding spiritual nature. We are suffering due to our forgetfulness of Kṛṣṇa and the blissful situation of His abode. If we accept the Lord as protector and shelter and execute His order, we can easily revive our eternal, blissful nature as parts and parcels of the Personality of Godhead. It is for this purpose that the Lord has created human life.”
