Acharya Prashant explains that Shri Krishna recommends physical acts of control, such as fixing the gaze between the eyebrows and regulating breath, because the body and mind are closely related. For most people who live in a gross dimension, it is difficult to detect or witness subtle thoughts, whereas physical actions are easier to perceive and record. By bringing the body to stillness, it is hoped that the mind will also achieve a certain stillness. While working directly on the mind is more fundamental and effective, many individuals are incapable of doing so and must start with the body as a preparatory step. Watching the inhalation and exhalation of breath serves as a gross parallel to watching the rise and fall of thoughts. Acharya Prashant clarifies that these physical techniques are stepping stones and a form of preparation for the real world of yoga. If one is subtle enough to work directly on the mind without attachment or prejudice, physical methods are not necessary; however, for others, it is helpful to start with the body.
