Rajas is a Sanskrit term from the Samkhya philosophy of Hinduism referring to “excitement, action, passion or force.” It is one of the three gunas (sattva, rajas and tamas), which together constitute all of the attributes of nature and the psyche.
Samkhya Yogi women who have taken celibacy vows and devoted their life to temple, idol of Ghanshyam Maharaj has been installed in Kalupur Swaminarayan temple and served by Sankhya Yogi women devotees.
Rajas is not to be confused with Raja (a king or prince). However, a monarch is likely to be well endowed in qualities traditionally ascribed to rajas. Saints would be stronger in sattva. And sloths in tamas.
Rajas also refers to a mysterious force said to be contained in vaginal fluid, which some yogis allegedly take inward through the urethra to facilitate mystical union. This may seem like a strange claim, but one has to remember that some yogis apparently perform unusual or amazing feats involving a level of mind and muscular control beyond the reach of most of us. Couple this with the Hindu belief in essential male and female forces, and the practice becomes more understandable.
