It is said that a Sadhu/Sanyasi can be of two kinds viz:
Vakta - One who communicates with the world through speech.
Mauni - One who does not speak butand keeps silence.
O dear Parvati, listen to me. There are two classes of knowers of Truth. They are (1) The Mauni and (2) The Vakta. No benefit accrues from the Mauni to any person. (Guru Gita)
My Questions -
A) Why does a Sanyasi choose to become Mauni? What purpose is served? Does becoming Mauni help in his path of sadhana in any way? Or is it just a matter of personal choice?
B) At what stage of spiritual advancement a Sadhu usually turns Mauni?
