Jalandhara Bandha

   

Jalandhar Bandha

 Another name for  Jalandhara Bandha is Chin Lock  or  Throat Lock .
This is the upper lock. In this bandha, you have to fold your chin onto your chest. The best way to do it is to lower your head onto your chest, but with your spine straight and only bend your neck, so your chin bends more towards your throat and thus your chin is closer to your chest. So you don't have to lower your head and your head doesn't come closer to your neck, but only your chin. At the same time, you close your throat. That is, as if you were suddenly holding back your swallowing.

So you can just lower your head to your chest or just bring your chin closer to your throat, your chest. Or you can simply do one of these or close your throat, your swallowing. Usually we use this lock during breath holding, or even before and during the chanting of mantras.  

For chakras:  crown chakra, sixth chakra, throat chakra, heart chakra and many others. It is used in meditation.
