Chinmaya Mission does not give mantra deeksha or initiate people as such.
Students who have completed the two year residential Vedanta Course at any one of the Chinmaya Mission’s Gurukula (Sandeepany Sadhanalaya -hyperlink) are given deeksha as Brahmachari/ Brahmacharini (in yellow robes) to serve across the globe for the propagation of knowledge. After a few years as Brahmachari they are initiated into sannyaasa and called Swami/ Swamini (in orange robes).
