This is a very interesting book. Presents different learnings and readings from different upanishads. There are a number of slokas given from the Upanishads. Kenopanishad, Mandukya Upanishad, Kathopanihad - all of them are quoted.

Inspite of all these, I found that this is not a heavy book. Even I could understand the flow of thought. I could follow the examples given and the stories picked up from the Upanishads.

The story of Nachiketa and his journey to yama loga and his three boons and his longing to understand what happens after death is well explained. The story of different sages seeking knowledge from different people is also explained.

It looks as if Kannadasan was right when he wrote in his tamil poem " Andavan satre arugil nerungi anubavam enbadhe naanthan enran". That is the story getting established by the discoveries of Bhrugu where he first identifies himself to the external things and then to his body and then discovers that there is something beyond this body.

All of us seek that experience which will make us understand everything else. It is like the question Parvati asks in the Vishnu Sahasranamam : "Kenopayena laguna vishnor nama sahasrakam?" Which nama, if I know, helps me know every other nama? That was the question. Our quests are also not very different. That knowledge, if I have, ensures that I don't have to seek anything else - that is what I need. What is that knowlege? That one thing, if I have, I don't have to have anything else. What is that? That is the voyage and that is the discovery.

Very well written. Worth spending the time reading it.
