The Isha Upanishad is one of one hundred and eight Upanishads.It comes from the last chapter of the Yajur Veda. Among Upanishads, it is one of the most important, because it teaches the fundamentals of consciousness. The Isha Upanishad presents a complete and coherent vision of life, knowledge, and action. A central teaching is that action and knowledge are not opposed.
Action without understanding leads to blindness; knowledge detached from responsibility leads to deeper obscurity. Liberation arises through their integration. Both metaphysical and analytical knowledge are necessary in life.They must be applied to life simultaneously if we are to live free from confusion and suffering.
