The four sounds of Om are: "Ah," "Oh," "Mm," and silence. These sounds represent different states of consciousness.
Here's a breakdown of each sound:
-
Ah (A): This sound originates from the back of the throat and represents the waking state of consciousness. It's the beginning, the creation, and the outward expression of energy.
-
Oh (U): As the sound moves forward in the mouth, filling the oral cavity, it transforms into "Oh." This represents the dreaming state and the inner world of thoughts and emotions. It signifies sustenance and preservation.
-
Mm (M): This humming sound is created by closing the lips and represents the deep sleep state, a state of absorption and dissolution. It is the union of the "A" and "U," representing the potential for creation and existence.
-
Silence: Following the "Mm," the silence is the fourth sound. This symbolizes the transcendental state of consciousness, beyond waking, dreaming, and deep sleep. It is the state of pure awareness and the ultimate reality, Turiya.
In essence, the four sounds of Om encompass the entirety of existence, from creation and manifestation to dissolution and the ultimate, silent reality beyond.
