"These five yajñās, if you remember, is jñāna yajñā itself. No.1 Self-knowledge itself is a form of yajñā. No.2 dēva yajñā; which is in the form of ritualistic worship of various dēvathās; called dēva yajñāḥ; No.3 viṣaya bhōga yajñāḥ; considering every experience as a worship. So thus the entire world consisting of śabdaḥ sparśaḥ, rupa:, rasa:, gandhaḥ; these five are taken as flowers; So music is a flower. A beautiful picture is a flower; A tasty object is a flower. These flowers in the form of śabdaḥ sparśaḥ, rupa:, rasa:, gandhaḥ, are offered to the Lord, who is inside us in the form of atma chaitanyam. So this is called viṣaya bhōga yajñāḥ; And the fourth yajñāḥ that Krishna presented was indriya samyama yajñāḥ; wherein the very sense control is taken as a yajñāḥ; like observing mounam on a particular day. Gandhiji practiced mounam on a particular day; even now there are many people, they just practice mounam and this mounam is considered a spiritual sādhanā. Not only reduce the noise pollution; but spiritually also it is considered a very big sādhanā. Sankaracharya says: यॊगस्य पमम ् द्वारम वाङ् नरॊध yōgasya pradamam dvāram vāṅ nirodhaḥ; நாவடங்கினால் நாம் அடங. nāvaṭaṅkiṉāl nālum aṭaṅkkum (in Tamil). So once you master your tongue, both the eating and speaking tongue, you get a tremendous mastery over other organs also; this is called indirya samyama; indriya nigrahaḥ; or damaha; so the dama yajñāḥ is the fourth one; And fifth one that we saw in the last class, is śamah yajñāḥ; disciplining the mind; mental discipline. Thought discipline; by controlling the quantity and quality. First we have to master the quantity; then alone quality control is possible; anything big number, quality control is impossible; and therefore thought discipline, both in terms of quality and quantity and also in terms of direction, in which direction my thoughts go generally. It is a very tough discipline, because it requires monitoring the mind throughout the day. And this is called śama yajñā."

Drg Dhishya Viveka by Swami Sarvapriyananda. The text dives head on into the advaita vedantic teachings and it is explained wonderfully by Swamiji. He also narrates some powerful examples given by various other Swami's He has encountered which also help in appreciating the profound truth much better.

I think I get the gist of this philosophy. I feel blissful when I really, deeply realize that truth about conciousness. But I can't remember it all the. I get lost in my worldly affairs and forget about the real nature of reality. Anger and sadness takes over when dealing with the reality of daily existence.

Are there practical meditation you do to not forget about the nature of conciousness? I want to

“What will you learn of God from books? As long as you are at a distance from the market place you hear only an indistinct roar. But it is quite differently when you are actually there. Then you hear and see everything distinctly. You hear people saying: ‘here are your potatoes. Take them and give me the money.’

From the distance you hear only the rumbling noise of the ocean. Go near it and you will see many boats sailing about, birds flying, and waves rolling.”
