The Kamakhya Temple in Assam celebrates the annual menstruation of the Goddess – and there is no idol there, just a structure that resembles the yoni, or the female symbol of creation.The Chengannur Temple in Kerala has a tradition of bathing the idol in a grand ceremony after her 'period' is over. According to the Kalika Purana, Kamakhya Temple denotes the spot where Sati used to retire in secret to satisfy her amour with Shiva, and it was also the place where her yoni (genital) fell after Shiva danced with the corpse of Sati. It mentions Kamakhya as one of four primary shakti peethas: the others being the Vimala Temple within the Jagannath Temple complex in Puri, Odisha; Tara Tarini) Sthana Khanda (Breasts), near Brahmapur, Odisha, and Dakhina Kalika in Kalighat, Kolkata, in the state of West Bengal, originated from the limbs of the Corpse of Mata Sati.

The temple remains closed for three days during the Ambubachi mela for it is believed that mother earth becomes unclean for three days like the traditional women's menstrual seclusion. During these three days some restrictions are observed by the devotees like not cooking, not performing puja or reading holy books, no farming etc. After three days devi Kamakhya is bathed and other rituals are performed to ensure that the devi retrieves her purity. Then the doors of the temple are reopened and prasad is distributed.On the fourth day the devotees are allowed to enter the temple and worship devi Kamakhya.

Many religions have menstruation-related traditions, for example: Islam prohibits sexual contact with women during menstruation in the 2nd chapter of the Quran. In Judaism, a woman during menstruation is called Niddah and may be banned from certain actions. Western civilization, which has been predominantly Christian, has a history of menstrual taboos.

Some Christian denominations, including many authorities of the Eastern Orthodox Church and some parts of the Oriental Orthodox Church advise women not to receive communion during their menstrual period. In certain branches of Japanese Buddhism, menstruating women are banned from attending temples.

In Japan, the religion of Shinto, the Kami, the spirits they worship, would not grant wishes if you had traces of blood, dirt, or death on you. In some portions of South Asia, there is a menstrual taboo, with it frequently being considered impure. Restrictions on movement, behaviourand eating are frequently placed.^[57] The Yurok in North America practiced menstrual seclusion. Yurok women used a small hut near the main house.

BONUS FACT: Hinduism is the only mainstream religion which worships God in the female form – for wealth (Lakshmi), education (saraswati), and courage too (Durga) – we worship Goddesses. What greater women empowerment can there be? To accuse Hinduism of gender disparity is beyond ridiculous!

With the advent of western education, especially missionary education, Hindus were made to feel that this whole ceremony is horrendous – how can you announce that your daughter has now started menstruating, what an embarrassment, how orthodox, what a shameful ritual, how backward – these were the things we were told. And instead of trying to resist, and make others understand what this ceremony meant, and its deep significance – we (me included) hung our heads in shame, relented, and agreed with them.

Today hardly anybody performs this ceremony for their daughters, because we were taught by those who came from outside that it is taboo, and shameful. We also joined the bandwagon which proclaimed menstruation to be 'filthy'.

Irony is that today, those very people who first advocated the stopping of 'shameful and orthodox' rituals of celebrating menstruation, are mocking Hindus about women entering Sabarimala and turning it into a 'menstruation taboo' issue, whereas clearly, it is not that at all.

So please stop trying to fool gullible people, because there are still many of us who know the truth. (Hindu Council Of Australia)
