"Hari Om Tat Sat"
The Great Yoga Guru Paramhamsa Swami Satyananda explains the meaning of Hari Om Tat Sat...
'Hari Om Tat Sat' is a very ancient mantra
from the Vedas. 'Hari Om' is one mantra and 'Om Tat Sat' another. I have joined
the two in 'Hari Om Tat Sat'. 'Hari' represents the manifest universe and life.
'Om' represents the unmanifest and absolute reality. By the word 'reality', I mean
total existence. You may even use the word God. Reality, existence, God, Brahman,
the absolute are all synonymous terms pointing to one being, but they do not really
This reality has two stages. One is the absolute, the other is manifest. This gross universe, the millions of suns, moons and stars, space, that which is beyond it and beyond this little earth, as far as we can go, are all manifestations of that reality, not a creation of reality. There is a difference between the process of creation and manifestation. You take cotton and make yarn from it, and then a shirt. The cotton has become the shirt, it has not created the shirt. The cotton has transformed itself into a shirt. In the same way, there is a great invisible force. Nobody can see it and nobody has seen it, except for a few people who we call avataras (incarnations).
The manifest reality, this world, is represented by the mantra 'Hari'. 'Om' is the unmanifest reality, the unseen, invisible, uncreated aspect of the absolute. So, 'Hari Om Tat Sat' means 'That is Truth'. That which I see with my eyes and that which is beyond my eyes are both the same, not different. The creator and the creation are not two. The creator has not created creation, but has manifested or transformed himself into creation.
All these truths are represented in the mantra 'Hari Om Tat Sat'. When I say 'Hari Om Tat Sat', it reminds me that the seen and the unseen, are both one.
