Definition: Drishti is a point of focus where the gaze rests during asana and meditation practice. Focusing on a drishti aids concentration, since it is easier to become distracted when the eyes are wandering all over the room. Each yoga pose has a specific drishti, which also aids in alignment. For instance, in Extended Side Angle Pose - Parsvakonasana the gaze is towards the raised hand, which also reminds us the turn our heads up towards the ceiling. Drishtis are particularly emphasized in Ashtanga yoga. Even though a drishti can be described as a fixed gaze, the eyes should always stay soft, never straining.
Examples:
In Downward Facing Dog, the drishti is your navel.
