The three states of consciousness—waking, dreaming, and deep sleep—are fundamental concepts in many spiritual and philosophical traditions, including Vedanta and Yoga.

1. Waking State (Jagrat): This is the state of consciousness where we are aware of the external world through our senses. In this state, we interact with our environment and perform our daily activities.
2. Dreaming State (Swapna): In this state, the mind creates a world of its own, independent of the external physical world. Dreams are often seen as a reflection of our subconscious mind, where desires, fears, and unresolved issues can manifest.
3. Deep Sleep State (Sushupti): This is a state of complete rest where there is no awareness of the external world or dreams. It is characterized by a sense of peace and rejuvenation. In this state, the mind is said to be in a state of potentiality, free from the disturbances of the waking and dreaming states.

In Vedanta, these states are often linked to the concept of Turiya, the fourth state, which transcends the other three. Turiya is considered the state of pure consciousness or the ultimate reality, where one experiences unity with the divine.
