๐ช Tradition & origins
- Nada-yoga โ the "yoga of sound" โ treats subtle inner sound (anahata nada, the "unstruck sound") as a support for meditation.
- It is described in the Nada Bindu Upanishad and in the fourth chapter of the Hatha Yoga Pradipika, and taught across several Indian lineages.
Tips to go deeper
- ๐กPractise in the quietest setting you can find.
- ๐กDo not strain to hear โ let the sound come to you.
- ๐กThe subtler the sound you can rest on, the more inward the attention becomes.
Common mistakes
- โStraining the ears or "hunting" for a sound.
- โWorrying whether the sound is "the right one" โ simply rest on whatever is subtlest.
What you may experience
- ๐Normal: a faint, steady inner sound; a naturally inward, absorbed attention.
- ๐Warning: distress about the sound (especially with tinnitus) โ stop and open the ears.
How to progress
Start with Bhramari (bee) humming to sensitise the ear to inner vibration, then rest silently on the subtle sound that remains.
โ ๏ธ Cautions
- If you have tinnitus or any ear condition, this practice may be unsettling โ do not close the ears, and consult a professional before focusing on inner sounds. Never insert anything into the ears.
