Vayu Mudra of Wind

With each hand bend the index finger so that its tip touches the ball of the thumb.
Then press the thumb lightly onto the index finger. Extend the other fingers in a
relaxed way.

For chronic complaints, do this mudra three times daily for 15 minutes; otherwise, use it until it has an effect. This position prevents "wind" (meaning flatulence), and a sensation of fullness, in all parts of the body. Ayurvedic medicine assumes that there are 51 types of wind in the body that produce numerous disorders.

These include gout, sciatica, flatulence, rheumatism, and trembling in the
hands, throat, and head. If you use the Vayu Mudra within 24 hours after an
outbreak of a disorder or disease caused by wind, you can very quickly count
on improvement. For chronic complaints, the Pran Mudra (Number 6) on
page 70 should be practiced. The Vayu Mudra must be discontinued as soon
as the disease disappears.
Too much wind in the body can be caused by inner waste substances,
particularly in the intestines, or inner tensions that are in turn based on
states of agitation. Frequently, the normal breathing rhythm (which is different
for each individual) is also disrupted.
As an additional measure, the "stomach contractor" can also be practiced.
To do this, assume the "cat posture." Inhale and lift your head some what; exhale and lower your head again while vigorously pulling in the abdominal wall at the same time.
During the pause in breathing, pull in the abdominal wall and let go of it several
times. Then inhale deeply again; raise your head again. Repeat the whole exercise a
number of times. In addition, the following visualization can help against tensions and
states of agitation.
