Vajrāsana - Thunderbolt Pose

Vajra = thunderbolt, adamantine, the weapon of Indra.

1. Sit back, straight up on your heels.

DURATION: Up to a minute
FOCUS: This allows the shoulder blades time to settle and allows any accumulation of tension to dissipate from areas like the front thighs.
Contraindications: If you feel any cramp in the underside of your feet or any tension or pain in the ankles, then put a rolled-up blanket underneath the front ankle joint and sit with a yoga block or wide cushion between your heels and buttocks.
The cushion can also be used where the knees are tight and it is advisable to sit on a blanket or other soft, even, stable surface.
