Srimad Bhagavatam 1.3.13
Human life is meant for subduing the modes of passion and ignorance and advancing in the mode of goodness.
Srimad Bhagavatam 10.10.8,
Human Life is meant for reviving one's eternal relation with the Lord and all religious injunctions are meant for awakening this dormant instinct of the living entity.
