Mandarava ( Skt., Mandāravā) ( Tib., མནྡཱ་ར་བཱ་; Wylie, ma da ra ba me tog) (also known as The Long Life Dakini Mandarava, Machik Drubpai Gyalmo, or Pandaravasini) was, along with Yeshe Tsogyal, one of the two principal consorts of great 8th century Indian tantric teacher Padmasambhava (Guru Rinpoche), a founder-figure of Tibetan Buddhism, described as a 'second Buddha' by many practitioners. Mandarava is considered to be a female guru- deity in Tantric Buddhism or Vajrayana.
There are a number of conflicting stories about the birthplace of Mandarava. According to some legends, she was born a princess in Zahor, Bengal in eastern India. while other sources, and some contemporary lore place this in Sahor, in Oddiyana (the Swat valley) of northern Pakistan, or near the city of Mandi, Himachal Pradesh, north-west India, where many shrines and important pilgrimage sites to Mandarava can be found today, such as the shrine to Mandarava above Lake Rewalsar pictured here.
According to legend, she renounced her royal birthright at an early age in order to practice the Dharma. Mandarava is known as being highly educated at a very young age, a rare accomplishment for a woman at that time. Mandarava's devotion led her to bring at least 800 women, including her entire personal retinue, to the path of the Dharma, all before meeting her teacher and consort, Padmasambhava.
Mandarava attained full enlightenment alongside Padmasambhava in the famed Maratika Cave in Nepal. She was a fully realized spiritual adept, a yogini, and a spiritual teacher.
