Value of One Second of Human Life
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.
Reaction of Karma
If one has killed an animal, one must himself be killed by that same animal. This is called mamsa. Mam means “me,” and sa means “he.” As I am eating an animal, that animal will have the opportunity to eat me.
Srimad Bhagavatam 10.10.14,
Srila Prabhupada
Reviving One’s Eternal Relation With The Lord
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.
Lust
Hankering after material happiness is called Lust & such activities are sure to meet with frustration in the long run.
