    Ardha Matsyendrasana is a derivative of the fuller pose, matsyendrasana (Purna matsyendrasana) named after the hath yoga revivalist, Yogi Matsyendranath [efn_note] Matsyendra [/efn_note]. Due to its challenging nature, Ardha matsyendrasana has been proposed.

    In Sanskrit, “Ardha” means “half”, “matsyendra” is “king of fishes”, and “asana” refers to “pose”. As it is an easier variant or half as tough as matsyendrasana, hence the name.

    People also refer to it by its English name, Half Lord of Fishes Pose. Sometimes, it is also known as the Half Spinal Twist pose, as it twists half of the spine performing the pose on one side at a time.

    In some texts, it is found by the name of Vakrasana. In Sanskrit, “vakra” means “twisted” and “asana” refers to “pose”. As it twists the body while performing the pose, hence also referred so.


    Mythology Behind the Pose

    The mythological tale associated with Ardha matsyendrasana is about Lord Shiva describing the yoga mysteries to Parvati (his consort). He took Parvati to a secluded island to describe yoga, a fish on the shore heard the conversation with concentration and remained still throughout.

    As soon as Shiva realized the fish has learned yoga, he sprinkled some water upon it. It enlightened the fish and it got into its divine form of Matsyendra (king of fishes). Matsyendra later returned to earth to spread yoga and take others to their spiritual paths.

    Some practitioners also have a perception that while holding the pose, the lower half of the body resembles the fish and another half the human. This shows the divine hybrid form of yogi Matsyendranath.
