By Swami Harshananda
Manana literally means ‘reflecting in the mind’.
This is the one of the three direct disciplines prescribed for getting the knowledge of the Ātman and its oneness with Brahman. It is defined as constant thinking of Brahman, already heard from the spiritual preceptor, strengthening it by logic which is in consonance with the purport of Vedānta.
