Baba Hari Dass Quote

Samyama, which is the application of concentration (dharana), meditation (dhyana), and superconscious trance (samadhi) in lightning succession, is practiced with the intent to gain specific knowledge of the object of concentration. The object is seen from all sides, in all its aspects, with full depth and breadth. As such, this complete absorption of the mind using the process of samyama brings complete and specific knowledge of the object. This power of knowing is vibhuti.
