Sri Nithyanandeshwara with Nithyanandeshwari is the presiding deity of the Nithyananda Dhyanapeetam. Nithyanandeshwara and Nithyanandeshwari are the forms of Shiva and Devi Parvati.
In the Vedic tradition, Shiva is the God of rejuvenation and embodiment of auspiciousness. Shiva is the first Enlightened Master on this planet Earth. Devi, the Cosmic feminine energy landed on planet Earth as Parvati, the daughter of the king of the Himalayan mountain and did intense penance in intense energy field of the foothills of the sacred hill Arunachala and actualized Her avataric mission on the Poornima day of the Vrishchika month (aka Karthika month) of the Vedic calendar. At that time, She actualized both the masculine energy and also the feminine energy within Her and experienced the form of Ardhanarishwara – the divine union of Shiva and Devi – in Herself. When this realization happened, She experienced the intense awakening of the Kundalini Shakti as a light shaft in Her spine.
Every year on the Poornima day of the Vrishchika month the planetary positions are such that the probability of Kundalini to get awakened in a seeker is at its maximum. Also like Devi actualized Shiva’s energy within Her, for one to experience Shiva’s energy and form, this is the best time to open themselves in the energy field.
Five thousand years ago Devi prayed to Shiva to reveal the secret techniques of Enlightenment for the benefit of the whole world. Pleased by the selfless prayer of Devi – the Cosmic Mother, Shiva revealed the great techniques of Enlightement which are later compiled as a scripture called “Vijnana Bhairava”, which consists of 112 techinques for Enlightenment. Nithyanandeshwara revealed these techniques to Devi exactly in the same place where the Nithyanandeshwara Temple is situated in the Bidadi ashram of Nithyananda Dhayanapeetam. Since Devi Nithyanandeshwari compassionately received the techniques for Enlightenment for the sake of us, Her actualizing Nithyanandeshwara’s energy within Her, is celebrated as Brahmotsavam for Nithyanandeshwara in the Nithyananda Dhyanapeetam.
This Brahmotsavam coincides with the Karthikai deepa brahmotsavam of the Arunachaleshwara Temple of Tiruvannamalai, the home-town of Nithyananda.
