Karma yoga is qualification for ghyan yoga. 

Whether grihastha ashram or Sanyas ashram we have to karma yoga sincerely and with satvikta in our actions

Karma shud be done with ishwar arpan buddhi - offering all your actions to the lord. You do the actions for the lord. And with the attitude of ishwar Prasad buddhi - accept the fruits of your karma whether pleasant or unpleasant as the blessing (Prasad of the god) 

Do your karma as Dharma - duty. 

With these attitudes the karma starts becoming satvik. It brings mental poise. 

Make spirituality top priority.
