If one ponders on objects of senses, there springs attraction, from attraction grows desire, desire flames to fierce passion, passion breeds recklessness.
Do your allotted work but renounce its fruit. Be detached and work. Have no desire for reward and work.
Contacts of the senses with their objects bring cold and heat, pleasure and pain. They come and go and are transient.
The wise man how is not disturbed or agitated – who is unmoved by pleasure and pain – he alone is ideal for immortality.
Know that to be imperishable whereby all this is pervaded. No one can destroy that immutable being.
– Bhagavad Gita
