It is my understanding that the development of Indigo and other abilities is a side effect of (and goes in tandum with) the process of spiritual awakening and the evolution of consciousness in human form. The realisation known as Enlightenment is the pinicle of this, and there have been some famous and many more less famous people who have come to this realisation. From Jesus Christ to the Buddha, there have been many teachers, though the ancient teachings have long become distorted, mistranslated, erroded and often grossly misinterpreted and misused. But there is still a discernable core of truth at the heart of most traditions, if you know what to look for.
I believe there are many people who could be described as 'Enlightened Masters', 'Buddhas' or 'Christs' alive today - human beings who have realised the absolute, the spiritual realisation that lies at the heart of all religious and spiritual practices.
Eckhart Tolle - now famous for his bestselling book The Power of Now and his webcasts with Oprah Winfrey, Tolle spontaneously realised enlightenment at 29 in the midst of a bout of suicidal depression, culminating in a total dissolution of the egoic self and the painbody.
Mooji, Gangaji & Eli Jackson Bear - Both Mooji and Gangaji come from the lineage of Sri Ramana Maharshi, and both became enlightened after meeting with Papaji in India, who's master was Ramana Maharshi. Eli is Gangaji's husband and a great spiritual teacher in his own right.
Osho (now desceased) - aka Bhagwan Sri Rajneesh - dispite the controversy surrounding Osho, he is widely recognised as one of the great spiritual masters of the 20th century, and his teachings are profound and insightful.
Having been to see Eckhart Tolle, Mooji and Gangaji at satsangs and talks, I can confirm in my own experience that all three are enlightened beings. I also believe that Osho was an enlightened master, as were Papaji and Ramana Maharshi. What I find most fascinating is that, whilst there is only one enlightenment, one spiritual realisation, each Buddha is clearly individual and has their own unique way of teaching, and a unique personality, and are still not 'perfect beings' so to speak. Eckhart Tolle said of himself that "I'm not perfect, but I am whole". As with most religions and spiritual practices, whilst there is only one goal, there are many roads that lead to it.
Other spiritual teachers I who appear to be enlightened (but I can't confirm) are:
Isira - an Australian woman who appears to be a Buddha.
Tyohar - who founded and resides at the spiritual village of Pacha Mama in Costa Rica.
Vishrant - an Australian spiritual teacher who gives Satsangs in Perth, Western Australia
Dolano - a German born woman who found enlightenment through the grace of Gangaji and also learned meditation from Osho.
Most of these have videos on YouTube and google videos, and they're deffinately worth checking out to see for yourself. If anyone knows more about these teachers or knows any others not mentioned, please post it here.
