Sri Isopanisad was written thousands of years ago in the Sanskrit language of ancient India and is the most confidential of the 108 Upanishads.
The eighteen jewel-like mantras of Sri Isopanisad can release us from the bleak, unsatisfying conceptions of modern artificial life.
These mantras provide, along with authers illuminating commentaries, key insights into the problems of modern civilisation ?unnessecery war, famine, poverty,polution of the enviornment  etc.?. And they show us how to harmonize our actions with the nature so that we can easily overcome and eradicate all our difficulties and always live peacefully and joyfully.
