What is karma yoga and how do I practise it in daily duties?
Karma yoga: duty offered to Bhagwan
Doing karma alone does not bring welfare, since its results must be experienced. Karma yoga means doing your duty by dharma, without desire for fruit, and offering it to Bhagwan.
Karma yoga is giving up desire for fruit, following your duty according to dharma and scripture, and offering that duty at Bhagwan's feet.
