Karmamudrā

 Karmamudrā (Sanskrit; "action seal," erroneously: kāmamudrā or "desire seal," Tib. las-kyi phyag-rgya) is a vajrayana buddhist technique of sexual practice with a physical or visualized consort. When the consort is a visualised one they are known as the jnanamudra. Purpose of karmamudra practice

Tantra uses skillful means to transform what could tie a practitioner to samsara into a spiritually liberative practice. Judith Simmer-Brown explains how karmamudra can be used to explore the nature of passion:

    There are traditionally three ways to realise the nature of passion in the yogic tradition of Tantra. First in creation-phase practice one can visualize the yidams as yab-yum in sexual union... Second one can practice tummo (caṇḍalī) or the generation of internal heat through the subtle body practices of the vital breath moving into the central channel. Third, one can practice so-called sexual yoga (karmamudra, lekyi chagya) with a consort. Realising the true nature of passion in all of these forms transforms ordinary passion into the basis for the experience of great bliss (mahasukha), which greatly accelerates the removal of emotional and mental obscurations in one's practice.

Early masters of the Six Yogas of Naropa, placed great emphasis on karmamudra practice, with some giving it separate status as one of the six yogas whilst others saw it as an aspect of the inner heat yoga. This sadhana is a part of the Lamdre system of the Sakya school, the Kalachakra tantra central to the Gelug school and Anuyoga as practiced by the Nyingma school.
Neccessity of karmamudra

According to most Tibetan Buddhist teachers, karmamudra is necessary in order to attain enlightenment in this lifetime. For example modern day Gelug teachers such as Thubten Yeshe and Kelsang Gyatso have both made statements supporting this view. However, some lamas disagree. For example the Dalai Lama, head of the Gelug school, refers to a commentary on the abbreviated Kalachakra tantra by Kaydrub Norzang-gyatso that says practitioners of especially sharp faculties can achieve the same objectives with solely a jnanamudra partner. He concludes "Thus it is not absolutely mandatory to rely on a physical karmamudra partner".
Qualifications for physical practice

In the 'new' schools of Tibetan Buddhism a practitioner of the three lower classes of tantra is restricted to visualisation of a jnanamudra consort. Initiation into one of the anuttarayoga tantras allows sexual practice with a karmamudra.

All Vajrayana traditions agree that qualified lay practitioners, including former monks who have given back their vows, can use physical consorts as the Vajrayana founders did. For example, Atisa wrote that "Those (consecrations) on which the householder may rely include everything taught in the tantras." There are different stances on whether current monks can engage in the practice. The Buddhist scholar Tripitakamala felt the overall goal of Buddhahood overrides concerns for monastic vows.

It cannot be practiced without the basis of the inner heat yoga, tummo, of which karmamudrā is an extension.
History

Tantra rose to prominence during the Pala Empire period in medieval India. Tantric Buddhism provided an alternative to the monastic solitary techniques to pursue enlightenment whereby it could be pursued through intimacy with Andover person. According to Miranda Shaw, the increased social inclusiveness of Tantra allowed the voices of women to emerge through their roles as karmamudra. Shaw details 16 known instances of women teaching male practitioners through secret oral instruction and notes that several of the 7 tantric texts accepted by the Tibetans in the 8th Century as fundamental tantric works were written by women.
Controversy

Judith Simmer-Brown notes that in Tibet there was a strong tradition amongst yogi outside the monastic communities of the practice of karmamudra. She states that these were primarily non-celibate practitioners such as terma text hunters, ngagpa and hereditary lamas within the nyingma and kagyu schools. However, she notes, their lifestyles sometimes scandalised the monastic communities, particularly those of the gelug, who valued strict monastic discipline.

Vipassana teacher Jack Kornfield quotes one unnamed female Buddhist teacher, wherein she talks about an "old" "realized" lama choosing a thirteen- to fourteen-year-old nun to become his sexual consort every year. After talking to "a number of Western women who had slept with their lamas" this same unnamed individual concludes the practice benefited only the lamas.

Academic, feminist and former kagyu nun June Campbell has spoken about women acting as karmamudra in secret sexual relationships with lamas, including one she claims to have had when she was in her late twenties with the incarnation of Kalu Rinpoche who died in 1989. In an interview with Tricycle: The Buddhist Review she states that at the time she didn't feel exploited but thinking about it over the years she came to see the demand for secrecy combined with an imbalance of power as similar to the techniques used by child abusers.
