Vajrasana
Explanation: 'Vajra' means diamond. The body is rigid as a diamond in this posture. This is a basic posture for many other asanas and meditation.
Description: Sit in the Dandasana posture. Place the palms on the floor near the thighs. Supporting your weight on the right palm, bend the left leg at the knee and pull the ankle under the left buttock.
Do the same with the right leg by supporting the body weight on the left palm. The toes point backwards and towards the ground while space is kept between the ankles. Do meditation with normal breathing or do Pranayaama with different breathing techniques in this posture for 10 to 15 minutes.
Benefits: Relaxes your kneecaps, knees, ankles and feet, improves digestion and reduces gas. Relieves sciatica pain. 'Vajrasana', if done for 10 minutes after a full meal relieves heaviness in stomach due to overeating. Note: Do not sit on the ankles.
