I'm simply against demonising the concept of religion. Naturally every religion that has grown influential enough for a larger group of people, which is true especially in the case of the three largest religions (Buddhism, Christianity, Islam), wars and other forms of bad things have been part of its history. But it's a different thing to say that religion is the reason for a war or that a religion has been involved in some ways in military conflicts. To blame the conquer of North American natives on Christianity is quite absurd. Isn't it that certain European kingdoms wanted to rule the whole place? Priests were neither military leaders nor government officials to eliminate the local population.
And let me repeat, I'm putting forth here an argument against the preconception that religion is something that creates wars. This is a view, a philosophical idea, and not a historical event. Religion includes all the religions, even the religions of Native Americans. It is not the same as saying there are religious militant groups and terrorists who use a religion as their ideology. Should we conclude that Buddhism causes wars because there were Buddhists warring? Is Buddhism as a religion faulty at slavery because there were Buddhists keeping slaves?
"While teachers of the middle way, mind only, transcendent wisdom, mantra, and other schools may have their own assertions, the fulfillment of those intentions is the same. There is not a single thing that is not contained within mind."
(Gampopa to Düsum Khyenpa, in "The First Karmapa", KTD Pub, p254)
“If you recognize the world of appearance and existence as the mind, realize the mind itself as empty, and have no grasping at the superiority of your realizations — this is the ultimate view."
