"The power to promote and reward, as also to demote and punish the individual and his fate in this world, lies within his mind, its thoughts and feelings. No external agency is necessary to bring this infallible fruition. As the growth and development of a seed, an embryo, or a cell designed and preserved by its own inner makeup, here too the causal forces for what one rightly deserves lurk within one’s own invisible bosom."
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.
