According to yogic texts, namaste is more superior to namaskar. Namaste is for divinity while namaskar is for another person.


In brief, namaskar is composed of three aspects

(a) The prefix 'namah' means 'I salute';
(b) The root 'kr' means 'do'; and,
(c) 'Ghain' is simply a standard Sanskrit suffix.

So: Namah - kr + ghain = Namaska'r

Namaskar means: "I pay my salutations" and it is understood that the
object of the address is the Supreme Consciousness that lies within.

Namaste is different.

Namah = Pay Salutations, Te = You; the meaning then is I salute You.

And the "You" refers to the Supreme Consciousness - not a human being.
That is why in various yogic traditions, namaste is only meant to be
done to the Divine Entity, whereas namaskar is for paying salutations to
the Supreme within another person.
