"Karmayoga does not mean ceaseless pursuit of karma. It truly consists in the Yoga orientation and discipline given to the buddhi and the mind. Constant preservation and application of Yogabuddhi while doing any work, alone makes one a Karmayogin."
The Guiding force of Narayanashrama Tapovanam & Center for Inner Resources Development
sanskrit: साधना; a sādhaka (spiritual aspirant) undertakes a pursuit (sādhanā) to attain the fruition (siddhi's). Generally speaking sādhanā is a discipline or dedicated effort undertaken in the pursuit of a goal, liberation in this case.
