I got introduced to this "Female Buddha" when I was looking name for my friend's daughter.
So what does female Buddha mean?
Wikipedia :
Tara (Buddhism)
Tara (Sanskrit: तारा, tārā; Tib. སྒྲོལ་མ, Dölma), Ārya Tārā, or Shayama Tara, also known as Jetsun Dölma (Tibetan language: rje btsun sgrol ma) in Tibetan Buddhism, is an important figure in Buddhism. She appears as a female bodhisattva in Mahayana Buddhism, and as a female Buddha in Vajrayana Buddhism. She is known as the "mother of liberation", and represents the virtues of success in work and achievements. She is known as Tara Bosatsu (多羅菩薩) in Japan, and occasionally as Duōluó Púsà (多羅菩薩) in Chinese Buddhism.
My question is what does this concept mean is she a person who appeared in past who's name is Tara?
Or is it philosophical concept that meditators seen she's appearing?
Also why this is not exist in Thervada Buddhism when statue is in Bihar state of India?
