But as a solitary practice devoid of submission of the will to God, he becomes an orphan, a teacher of a Godless philosophy of life, an exalted humanism.
A belief in a personal God just isn't critical to his spirituality. That's not to say he denies the existence of God, of course not. But I'm guessing he sees the personal God as a stepping stone to deeper realizations. Of course its a solitary practice, but again, he's mostly trying to reach people turned off by organized religion, authority, and hierarchy.
Tolle is all about self introspection as an end in itself, the religion of Jesus was about self forgetfulness, love and service to others, a dedication to doing the will of the Father as the central focus of life.
I think its more like Paul on Mars Hill. He taps into something many people find elusive, any sense of sacredness, and he finds a way to get in touch with that. That's a huge step.
Westerners are so used to just accepting the guilt narrative (probably owing to the teaching on Original Sin), its hard to think of any other kind of spirituality that isn't based around it, so I think even people like Rohr hesitate. The emphasis on love and service, that's something that Richard Rohr also emphasized as a perceived weakness with Tolle's teachings. But I think it's a potentially misguided concern. I really don't think people can be commanded or guilted into "loving your neighbor as yourself". On the other hand, teaching people to be happy and content without having to indulge what Tolle calls "the pain body" is hugely significant, and it echoes a teaching I've heard from some Buddhist teachers, when happiness is available for little or nothing, people just don't pursue lesser goods and cause suffering for others. A world where people don't go around hurting others carelessly is essential to love, indeed, Paul says this is the whole of Torah.
I've heard it said before by some liberal Christians, Buddhists are just more comfortable in their own skin. In my experience, being comfortable in your own skin is essential to being the kind of person that can genuinely love.
