It is of note, to me, that during this time of questioning “the nature and origins of postural yoga (asana),” (as it is stated on the back of Mark Singleton’s 2010 book, Yoga Body) that somehow I have chosen to study a concept that connects to the yogic texts that are from India.
In Moola Bandha, The Master Key, by Swami Buddhananda there are several references to traditional texts. Mulabandha is mentioned in the Hatha Yoga Pradipika (15th century CE) as “one of the practices which annihilate old age and death.” According to the Gheranda Samhita (late 17th century), mulabandha is the “destroyer of decay.” The Siva Samhita states (17th or 18th century, or before 15CE), “If in the course of practice of this bandha (energetic lock), the yogi can unite the apana (downward-moving subtle energy) with the prana vayu (subtle energy principle), then it becomes yoni mudra. One who has accomplished yoni mudra, what can he not accomplish in the world?” It is also mentioned in several of the Upanishads (from before 5th century BC to as late as 1926). According to the Yoga Shikha Upanishads (probably originating from the 13th century) and some other Upanashads the mastery of practice brings “siddhis (psychic abilities).”
Also interesting is the statement from Moola Bandha, The Master Key, “Scriptural descriptions all relate to the male body.” And, “The actual point of physical contraction varies according to sex.”
I definitely plan to look into the physiology and potential of what can happen in the pelvis, by further study in Moola Bandha, The Master Key (The first edition was published in 1978.), and by looking into more recent information available on the subject.
