Meditation

Meditation is a mental discipline where a person attempts to enter a deeper state of peace and awareness.

Vulcans often practised meditation to keep their emotions under control. During the Pon farr meditation could be used to try and control the strong emotions experienced. 

One Vulcan technique was called F'as'al. ("Father to the Man")

Maxine Benton studies Vulcan meditation techniques at Starfleet Academy but found them too difficult to master.

While on leave on Bajor in 2374, Jonathan Masters practised a meditation technique that the monks at the Bajoran monastery had taught him.
