The Scriptural Commentaries of Yogiraj Sri Sri Shyama Charan Lahiri Mahasaya

"In the middle of the eyebrows, at the root of the nasal passage, is the abode of Nectar; if one abides there--the One Who resides there--it is He that is Eternal; He is Omnipresent; thus Supreme."
--Yogiraj Lahiri Mahasaya from Commentary on Krishana-Yajurvediya Dhyanabindu Upanishad
"Throw vayu up into space, abide as no-self in the par avastha of Kriya, remain only in Brahman with breath sealed in Brahman and do "yunjana." Via this, there will be "rechak"--meaning: you will be Still."
--Yogiraj Lahiri Mahasaya from Commentary on Krishana-Yajurvediya Amritabindu Upanishad
"Remain steadfast in the poise of Kriya and proceed accordingly and all will be good."
--Yogiraj Lahiri Mahasaya from the Garland of Letters
