Udyoga Parva 42.11

The remembrance of earthy enjoyments is the first cause of death to men; afterwards come desire (to have those enjoyments) and anger (at the failure to have enjoyments from or other). These (i.e. the remembrance of enjoyments, desire and anger) cause death to be met with by boys (men of little sense); but those that have successes in controlling their souls cross over death unharmed by means of their self-restraint.
