Namaste is a Sanskrit word; The best translation I found is from Ace the Himalaya Travel :
My soul honors your soul.
I honor the place in you where the entire universe resides.
I honor the light, love, truth, beauty and peace within you
because it is also within me.
In sharing these things, we are united.
We are one.
Questions to Consider
Can you clearly see that we’re one, and still chop the wood, and carry the water?
How can you tell that the person is enlightened?
