Overview of Chapter 2 – Mandukya Upanishad
Chapter 2 of the Mandukya Upanishad elaborates on the four states of consciousness—waking, dreaming, deep sleep, and Turiya—by examining their qualities and functions. It explains how the waking state (Jagrat) is outwardly focused and engages with the physical world through the senses. The dream state (Svapna) is inwardly focused, where the mind creates experiences independent of external objects. Deep sleep (Sushupti) is a state of unified consciousness, free from desires and mental modifications. Turiya, the transcendent fourth state, remains ever-present, pure, and blissful, beyond the three ordinary states. The chapter emphasizes that understanding and abiding in Turiya leads to true knowledge and liberation (moksha), revealing the non-dual nature of the Self (Atman) as identical with Brahman.

Shankaracharya’s Insights on Chapter 2 – Mandukya Upanishad
Adi Shankaracharya explains that Chapter 2 elaborates on the four states of consciousness and their relation to the ultimate Self. He emphasizes that the waking (Jagrat) and dreaming (Svapna) states are phenomenal and marked by duality, while deep sleep (Sushupti) shows bliss but lacks awareness of individuality. Beyond these three lies Turiya, the fourth state, which is pure, non-dual, and eternal consciousness, untouched by mental modifications or worldly experiences. Shankara interprets Turiya as the true Self (Atman), identical with Brahman, which alone is real. He stresses that the letters of Om symbolize the three ordinary states, while the silence following Om points to Turiya, which can only be realized through meditation, self-inquiry, and direct experience. According to Shankara, recognizing Turiya dispels ignorance, duality, and suffering, leading the aspirant to liberation (moksha). Thus, Chapter 2 reinforces the Advaita Vedanta teaching of non-duality, showing the path from apparent multiplicity to the ultimate reality. For More Information Click Here
