One second of human life wasted in the vain research of planning for happiness in the material world can never be replaced even if one spends millions of coins of gold.
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.
The human life is meant for attaining eternal and unlimited happiness by spiritual realization.
Srimad Bhagavatam 1.3.13
Because human life is a combination of matter and spirit soul, the whole process of Vedic knowledge is directed at liberating the spirit soul from the contamination of matter.
Srimad Bhagavatam 2.1.3,
The human form of life is rare and valuable.
Srimad Bhagavatam 2.3.2-7,
