In Hinduism
Shaktism (Shakta philosophy)
Source: Google Books: ManthanabhairavatantramYonimaṇḍala (योनिमण्डल) refers to the “maṇḍala of the Yoni”, according to all three of the basic Kubjikā texts, the Kubjikāmatatantra, Ṣaṭsāhasrasaṃhitā and Śrīmatottara.—Accordingly, “Everything generated within the Three Paths [i.e., tripatha-anta-samudbhava] is tranquil and has been placed in the (half-measure consisting of) three measures. Without the Three Paths the maṇḍala of the Yoni [i.e., yonimaṇḍala] does not manifest. Without the Yoni there is no success (niṣpatti) in divine and profane matters. It is present (in all that is) most excellent, middling and the least. The three measures (mātrā) are said to be the Point, Power (śakti) and Sound. The abode, which is the Yoni (bhagālaya), is formed by the union of these three conjoined with the supreme half-measure that is (known as) Praṇava in the Kulāgama. Conjoined with the letters A, U and Ma, this Praṇava is action. [...]”.

Shakta (शाक्त, śākta) or Shaktism (śāktism) represents a tradition of Hinduism where the Goddess (Devi) is revered and worshipped. Shakta literature includes a range of scriptures, including various Agamas and Tantras, although its roots may be traced back to the Vedas.
Yoga (school of philosophy)
Source: ORA: Amanaska (king of all yogas): A Critical Edition and Annotated Translation by Jason BirchYonimaṇḍala (योनिमण्डल) refers to a “(woman’s) vagina”, according to the Yogamārgaprakāśikā 145-146b.—Accordingly, “If [the Yogin’s] semen accidentally moves [from his body] and has fallen into [a woman’s] vagina (yonimaṇḍala), the sucking up of both [semen and vaginal fluid] by the Yogin, [results in] him becoming a receptacle of [all] the Siddhis. This Mudrā, [called] Sahajolī, should always be known by Yogins”.

Yoga is originally considered a branch of Hindu philosophy (astika), but both ancient and modern Yoga combine the physical, mental and spiritual. Yoga teaches various physical techniques also known as āsanas (postures), used for various purposes (eg., meditation, contemplation, relaxation).
