According to Yoga philosophy, the process of Chhath is divided into six stages of the Conscious Cosmic Solar Energy Infusion Technique (Conscious Photoenergization Process).

Stage 1: Fasting and the discipline of cleanliness leads to detoxification of the body and mind. This stage prepares the body and mind of the Vratti (devotee) to receive the cosmic solar energy.

Stage 2: Standing in a water body with half the body (navel deep) in the water minimizes the leak of energy and helps the prana (psychic energy) to move up the sushumna (psychic channel in the spine).

Stage 3: Cosmic Solar Energy enters the Vratti's pineal, pituitary and hypothalamus glands (Triveni complex) through the retina and optic nerves.

Stage 4: Activation of Triveni tri-glandular complex (pineal, pituitary and hypothalamus).

Stage 5: A kind of polarization of happens in the spine, which results in the Vratti's gross and subtle bodies getting transformed into a cosmic powerhouse. This can also lead to the awakening of the latent psychic energy popularly known as the Kundalini Shakti.

Stage 6: The body of the Vratti (devotee) becomes a channel which conducts, recycles and transmits the energy into the entire universe.
