This twist of the thirteen limbs is called Matsyendra-pīṭha, so named by the yogīs of the three worlds.

This verse concludes the description of Matsyendrāsana with additional information about its name and meaning.

Trayodaśāṅgānām — “of the thirteen limbs” — is a technical expression that may refer to:

• The thirteen major joints affected by the twist
• The thirteen components of the subtle body
• A traditional classification of body parts

Parivṛttaka — “twist” or “rotation” — describes the principal action of the posture.

Matsyendra-pīṭha — “seat of Matsyendra” — is another name for the posture, honoring the legendary master. Pīṭha means seat or throne, suggesting this was Matsyendranātha’s preferred posture for meditation.

Bhuvana-traye — “in the three worlds” — indicates the universal renown of the posture. Yogīs of all planes of existence recognize its value.

Matsyendranātha is a semi-mythical figure. According to legend, he was a fisherman who accidentally overheard the secret teachings of Śiva to Pārvatī while inside the belly of a fish.
