Where the word comes from
The root is linked to verbs meaning to bind and to hold, which is why it is usually translated as "lock". Traditional descriptions of yoga name three main bandhas (mula, uddiyana, jalandhara): in the pelvic area, the belly and the throat. Teachers explain them in different ways today, and there is no single description.
There is no need to wrap the word in mystery. In class a "lock" most often means a deliberate but calm engagement of muscles, nothing unusual.
How to say it
Say BUN-dah, with the stress on the first syllable; the "ndh" runs together and the word ends on "a". The vowel in both syllables is short, so the word runs evenly.
A teacher usually says the name of a particular bandha aloud and shows it. If you are unsure of the pronunciation, do not worry: nobody expects a perfect sound.
The names of the three bandhas are Sanskrit as well: mula bandha, uddiyana bandha and jalandhara bandha. You need not memorise them; a teacher usually names only the one that is needed.
What it looks like in class
A teacher may say "draw the lower belly in a little" or "gather the muscles of the pelvis". That is bandha in everyday words. Such cues often come in plank, in balances and in transitions where the trunk has to stay steady.
The engagement should be light: your breath stays free and your shoulders and face stay soft. If you hold your breath or tense up, halve the effort. A beginner only needs to follow the cues and not chase a perfect sensation.
Bandha next to other words
You will hear bandha most often alongside pranayama and dynamic practice: in vinyasa and ashtanga the teacher asks you to keep the trunk lightly steady while you breathe and move. In such classes the cue sounds like "gather yourself" or "draw the lower belly in".
A useful test for a beginner: after the cue you can still breathe calmly and speak. If not, the effort is too large. The word "lock" does not mean rigidity; it is more like a soft support. In plank it feels like being gathered together, while calm styles hardly mention bandha at all.
Common misunderstandings
- "A bandha has to be held as hard as possible." The effort is small and gentle, and the breath does not stop.
- "Yoga does not work without bandhas." At the start you can simply move and breathe, and the teacher's cues will come naturally.
- "It is the same as working the abs." Bandha is about attention and steadiness of the trunk, not a number of repetitions.
