Ardha means half. Chandra is the moon. The pose resembles the
half moon, hence the name.

Technique

Stand in Tadasana and then do Utthita Trikonasana,
following the technique described earlier.

After attaining Trikonasana on the right side, exhale and place the
right palm about a foot away from the right foot by bending the right
knee and at the same time bringing the left foot near the right one.

Wait in this position and take two breaths. Then exhale and raise
the left leg from the floor, toes pointing up. Stretch the right hand
and the right leg.

Place the left palm over the left hip and stretch up, keeping the
shoulders well up. Turn the chest to the left and balance.

The weight of the body is borne on the right foot and hip. The right
hand is only a support to control the balance.

Hold the pose from 20 to 30 seconds, breathing deeply and evenly.
Then slide the left leg to the floor and go back to Trikonasana.

Repeat the pose on the left side.

Effects

The posture is beneficial for those whose legs are damaged or infected.
It tones the lower region of the spine and the nerves connected with
the leg muscles and it strengthens the knees. Along with other standing
postures, this asana cures gastric troubles.

Note

Those who feel weak and are exhausted by the standing poses
should only practise Utthita Trikonasana and Utthita
Parsvakonasana (Plate 8), as these two asanas strengthen the body.
The other standing asanas should be done only by people who have
built up their strength and whose bodies have become elastic.
