Remi just uses instagram, as far as I know. His username there is brotherofosiris. He deleted a while back because of conflict with other bloggers here and also I believe he felt (and I agree) the magic of tumblr and the community we used to have between 2010 and 2012 kind of crumbled and mutated itself into wishy washy new age “love and light” narcissists with delusions of grandeur. And I dont think he wanted to associate with that. But I cant really speak for him so maybe you should ask him yourself.
Nirvikalpa is to date the best blog I’ve ever followed, Remi’s blog has inspired me in ways no other blog has, and he has taught me so much about life and love.
