"It is not what you do that matters, but how you do it – with what attitude and aim. The spiritual effect that a seemingly spiritual activity brings, can also be had by the domestic pursuit, provided you preserve a spiritual attitude and dedication."
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.
