"Devotion is a means as well as its true end when it grows into a full treasure. When devotion becomes a treasure, you will need nothing more for inner fullness or affluence. As devotion grows, it will begin to free you of all desire, hatred and fear. It will relieve poverty, either by making you amply resourceful or by taking away from you the very feeling of poverty. Devotion also will remove your weakness, generating untold strength and confidence."

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.
