Dravya Yagna: Charity and distribution of honestly acquired wealth in a spirit of devotion in the service of the community is called Dravya yagna. Wealth includes love, kindness, sympathy and affection also.

Tapo Yagna: Offering of a life of austerity to The Lord in a spirit of dedication so that the seeker may attain a little self-control.

Yoga Yagna: Yoga is an attempt to grow from the lower in us to the higher standard of divine living; it comprises such practices as breath-control and the withdrawal of the mind from the objects of the world.

Swadhyaya Yagna: This means study and understanding of the scriptures without which no progress in spiritual practices is possible. It also implies introspection.

Jnana Yagna: It is that activity in man by which he renounces all his ignorance into the fire of knowledge kindled by him in him. This has two aspects – negation of the false and assertion of the real nature of the Self. These two activities are undertaken during the seeker’s meditation.

All these five methods of self-development can be practiced only by him who is sincere and consistent in his practices.
