The collective electrical impulses from our brain produce brainwaves. Brainwaves are generally broken into five main frequencies, with each serving a different purpose:
Delta (1 - 4 Hz) -- associated with deep sleep and recovery
Theta (4 - 8 Hz)-- associated with light sleep, highly receptive state
Alpha (7.5 - 13 Hz) -- associated with mental clarity and new learning
Beta (13 - 30 Hz) -- responsible for fight-or-flight response
Gamma (30 - 44 Hz) -- associated with formation of ideas, memory processing, and compassion
At any one time, our brain is operating with a combination of the above brainwaves, with one usually being predominant.
When our brainwaves are out of balance, this is associated with any of a number of emotional and neuro-physical health problems.
Gau (producer) performed an extended Vedic fire ceremony that accompanied evening Agnihotra on Jan 2, 2021. The fire ceremony lasted for about 2.5 hours, involved many Mantra, and included offerings of ghee to a specially prepared fire on the utterance of "Swaha."
Below is a screenshot of absolute brainwaves during a portion of the fire ceremony in which "Swaha" was recited and a fire offering of ghee was made rhythmically every handful of seconds.
1. Delta waves are predominant, indicating a deep state of relaxation. Theta waves were next predominant, indicating a relaxed, receptive state.
2. The delta, theta, alpha, and beta brainwaves followed roughly similar cyclical upward and downward slopes throughout the ceremony. Gamma waves showed a different trend.
3. The rise, peaks, and falls of the delta, theta, alpha, and beta brainwaves follow similar time markers.
4. The absolute amplitudes and changes in the delta, theta, alpha, and beta brainwaves seemed maintain a proportional ratio.
5. The delta, theta, alpha, and beta brainwaves had corresponding steep downward slopes, following the utterance of "Swaha" and offering of ghee to the fire.
6. The delta, theta, alpha, and beta brainwaves appeared to converge on the utterance of "Swaha".
What do the cyclical brainwaves mean? What does it mean for the delta, theta, alpha, and beta brainwaves to follow similar cyclical patterns, with proportional changes and amplitudes? What causes the downward slope of the brainwaves on the utterance of Swaha and making the fire offering? Why do the brainwaves converge on the utterance of Swaha and making the fire offering?
Is this some form of brainwave harmonics induced through the Vedic fire ceremony?
These are interesting findings that are worth exploring further.
