Blavatsky & Dharmapala bio - Lion's Roar

The Lion’s Roar: Anagarika Dharmapala and the Making of Modern Buddhism, Sarath Amunugama, pp i-vii, 1-719, VijithaYapa, Colombo, 2016.

An early convert to Theology led by Blavatsky and Olcott, his non-commitment to Buddhist Theology took him to the Theological movement’s headquarters in Adyar and from there to the recovery of the Buddhist places in British India. In the last decades of his life, the recovery of the Buddhist sites became one of principal objectives of his life; in particular save Buddhagaya from the control of the Hindu Mahants. This was something he could not achieve in his life time, but he had led the way and his success in the historic processes of Buddhist recovery succeeded in establishing Buddhism as a civilizational influence internationally. For instance his creation, the Mahabodhi was the main facilitator of Ambedhkar’s decision to covert to Buddhism with the millions of his caste fellows, the dalits.

Dharmapala and early TS history:
Anagarika’s efforts to foster Buddhism in Asia began in Adyar - Dr. Sarath Amunugama
“It was during this week in Adyar that he was instructed by Blavatsky to study Pali. Impressed by the gathering in Adyar, Dharmapala vowed “that henceforth my life should be devoted to the good of humanity.” In 1886, he accompanied the Ramanya Nikaya monk Ilukwatte Medhankara to Adyar. Medhankara was a favourite of the ‘Theosophical Twins’ Blavatsky and Olcott: “A word must be said about this Medhankara. He was of the Ramanya Nikaya, a young man truly holy in his life and aims to a degree that I have never seen equaled among the Bhikkus of Ceylon.”

Political commentary on Dharmapala:
Has Modi found a Buddhist Vivekananda in Anagarika Dharmapala?
Ranjan Crasta At an early age, even as he was educated in Christian institutions, he found himself drawn towards Buddhism. This affinity to Buddhism was eventually cemented when Colonel Olcott and Madam Blavatsky, two of the founders of the Theosophical society in Britain began visiting Ceylon and declared themselves Buddhists. A 16-year-old Dharmapala grew close to the two, assisting Olcott as a translator as he travelled around Sri Lanka furthering Buddhist education. https://sgforums.com/forums/1728/topics/490312/
