Acharya Prashant addresses a question about lucid dreaming in the context of Ramana Maharshi's teachings on the three states of consciousness: waking, dreaming, and deep sleep. He begins by calling the idea of lucid dreaming as a higher state of consciousness "tremendous stupidity." He clarifies that Ramana Maharshi's point is that the three states are one because they all belong to the ego (Ahankar); the "I" is at the center of all three, and "I-ness" remains throughout. Otherwise, the states are very distinct, and the scriptures even provide different names for the "I" in each state, such as Vaishvanar for the perceiver in the waking state (Vishva) and Taijas in the dream state. The speaker refutes the concept of being consciously asleep, arguing that sleep is already a state of consciousness, just like dreaming and waking. All these states are flawed because the ego is at their center. He explains that when one is dreaming, one is conscious within that dream world, and it feels real. Similarly, the waking state can be an illusion, like a mirage. He dismisses the modern movement of lucid dreaming, comparing it to someone sleeping in their office during waking hours and questioning if that is a spiritual flowering. He asserts that being half-awake in sleep is a sign of a disease like insomnia, not a spiritual accomplishment. Acharya Prashant then explains the true spiritual state, which Vedanta calls "Jagrat Sushupti," or being awake in deep sleep. This does not mean literally being awake while the body sleeps. Instead, it describes the state of an awakened man who, while his eyes are open and he sees the world, remains internally as unperturbed and tranquil as a person in deep sleep. The spiritually awakened man sees everything but does not identify with or relate to it. His peace is like that of a sleeping man who is undisturbed because he does not see anything, but the awakened man is undisturbed even while seeing everything. The practice to achieve this state, he emphasizes, must happen in the waking state, as it is the only state where one can receive and apply instructions. By learning to remain untouched, undisturbed, and uninvolved throughout the day, there is a great chance that one will remain detached even in dreams. He concludes that experimenting with dreams is a childish trick that will only result in bad sleep, and the real practice of non-identification must be done in the waking state.
