For our intellectual mind it is a satisfying experience to know the purpose and meaning of everything.

It can be noted that at the time of the chanting there is not much of a need to contemplate on the meaning of the mantra.

There is a special category of Mantras called Contemplative Mantras, whose meaning has to be Contemplated upon as they are chanted.

Mantra "SOHAM"(the sound of our breath) is a Contemplative Mantra. It means "I AM THAT".
