Acharya Prashant explains Shri Krishna's teaching to Arjun from the Bhagavad Gita regarding the control of the restless mind through practice and detachment. He clarifies that in spirituality, practice does not mean mere repetition or following specific routines, as the mind is already filled with habits and routines. Instead, practice signifies constant alertness and staying centered in the Self while observing the mind's activities from a distance. He emphasizes that spirituality is not about adding new actions to one's life but about bringing a sharp, subtle vision to existing actions and thoughts. One should observe their own body, gestures, and speech to gain insight, as meditation is not a separate act to be performed at a specific time but a state of being.
