Manas — the mind · door 1 of 1
Tarang — the five waves of the mind
Delta, theta, alpha, beta, gamma: what science measures, and what the rishis saw
The wave dial
Turn the dial. Watch the wave quicken and slow, and see the state it belongs to.
Alpha · 8–12 Hz
Relaxed, eyes closed, awake
Calm and present. Close your eyes and breathe — this is where you arrive.
Shift it yourself: beta to alpha
Ninety seconds. Thinking, worry and the screen keep the mind in beta; this walks it, step by step, toward alpha.
Why it works: closing the eyes is the most reliable way to raise alpha known to science (first seen in 1929). A breath out longer than the breath in, around six breaths a minute, calms the body's alarm. Wide, soft vision quiets the narrow focus that beta holds.
VEDAUM cannot see your brain waves. What you can notice is the felt shift — and that noticing is the practice.
Every crossing, and how it is made
- Beta → AlphaClose the eyes. Lengthen the out-breath. Soften the gaze. The shift above.
- Alpha → ThetaLie down. Yoga nidra, or a slow body-scan. Let images come and go without holding them; that drift is theta's edge.
- Theta → DeltaThis one you cannot do; you allow it. A dark, cool room, the same hour each night, no screen in the last hour.
- Scattered → steady betaOne task, one window, one breath before you begin. Beta is not the enemy; scattered beta is.
- Toward gammaNo shortcut, and no sound or app that delivers it. It was found in people with years of daily practice. The path is the sitting, kept.

The rishi's four states
The Mandukya Upanishad names four states of consciousness. Turn each card to see the wave set beside it.
A parallel drawn by VEDAUM — not a claim of the Upanishad, and not a finding of science.

Three questions to seal this door
1. Which wave dominates deep, dreamless sleep?
2. Close your eyes and relax. Which wave rises?
3. Which band did studies find unusually strong in long-term meditators?
The rishi's scroll — read more, if you wish
Every moment, billions of neurons fire together in rhythms that an EEG — sensors on the scalp — can measure in cycles per second (Hz). The rhythms fall into five bands: delta, theta, alpha, beta and gamma. Every human mind moves through all five every day. No band is good or bad; each belongs to a state.
Close your eyes and relax, and alpha reliably rises — one of the most repeated findings in the science. Studies of long-practising meditators have found unusually strong gamma. These are real, measured differences — and they are what a practice can work toward, not what an app can see.
What VEDAUM will never claim: it cannot measure your brain waves — a phone has no EEG — and no track here is said to put your brain into any band; the evidence for that is weak and mixed. The Mandukya Upanishad's four states are set beside the waves as a parallel, not a proof.
| Wave | Cycles per second | State |
|---|---|---|
| Delta | 0.5–4 Hz | Deep, dreamless sleep |
| Theta | 4–8 Hz | The edge of sleep, deep meditation |
| Alpha | 8–12 Hz | Relaxed, eyes closed, awake |
| Beta | 13–30 Hz | Active thinking and focus |
| Gamma | 30–100 Hz | High focus and integration |
