Why this practice

Pairing mantra with breath anchors the mind for meditation and weakens the pull of outward distraction. A gateway to deeper Kriya practice.

Silently chanting Hong on the inhale and Sau on the exhale while observing the natural breath turns breathing into a meditation anchor. A foundational Kriya Yoga technique taught by Paramahansa Yogananda, designed to draw attention inward and quiet the mind. The sounds are Sanskrit and together mean I am That — a reminder of the breath's deeper nature.

The science behind it
Coordinating a short silent mantra with the natural in‑and‑out breath (Hong on the inhale, Sau on the exhale) couples two stabilizing influences: the mechanical act of nasal breathing and a simple attentional label. Nasal, unforced breathing tends to engage vagal afferents and increase parasympathetic tone, which shows up as higher heart‑rate variability (HRV) and a measurable “relaxation response.” That physiological shift reduces sympathetic arousal (fight/flight signals) and supports calmer autonomic regulation without needing exaggerated breath changes.

At the neural level, silently repeating a mantra while observing the breath directs attention inward and strengthens interoceptive awareness (the felt sense of the body and breath). This anchors activity in attention and insula-related networks and reduces mind‑wandering from the default‑mode network. A practical safety note: because Hong‑Sau uses natural breathing it avoids the CO2 imbalances and lightheadedness that can come from forced rapid or overly shallow breathing; if dizziness or tingling occurs, return to normal breathing and pause the practice.

Do not force the rhythm. Let the orb suggest timing while the mantra rides the breath as it is.

Natural breath at the nostrils. Hong on the in-breath, Sau on the out.

How to practice

  1. Sit upright with eyes closed or softly lowered.
  2. Let the breath be natural through the nose. Do not control its depth or pace.
  3. Watch sensation at the nostrils as the breath flows in and out.
  4. As the breath flows in, mentally chant Hong (rhymes with song).
  5. As the breath flows out, mentally chant Sau (rhymes with saw).
  6. When thoughts arise, return gently to breath and mantra. No strain.
  7. Let the counting orb be a soft companion, not a command.
