Definition - What does Dhi mean?
Dhi is a Sanskrit word that has several meanings all related to the activities of the mind. It can be translated as “intellect,” “understanding,” “imagination,” “opinion,” “notion,” “true knowingness” and even “mind.” As a verb, it means “to place” or “to hold” and indicates the mind as a vessel or receptacle for thoughts.
In Hindu philosophy, none of these translations quite captures the meaning of dhi. It is more of the intellect's processing of a particular thought, like a gut feeling or intuition. The dhi must be convinced for a thought to be accepted.
Yogapedia explains Dhi
Dhi forms two words that are key concepts in Hindu and yoga philosophy – dhyana and samadhi. Both are steps in Patanjali's eight-limbed path of yoga as described in The Yoga Sutras.
Dhyana – dhi plus yana (moving or going) – is generally translated as “meditation,” but refers to a practice that is deep meditative concentration.
Samadhi – sama (together) plus dhi – is the final limb of yoga. It is complete concentration that indicates the mind's ultimate state of being, or enlightenment.
