This is all about releasing the blocking mechanism that exists. I feel people like Eckhart Tolle have somehow mastered this, at least in the realm of the scope of abilities they are most comfortable being confined in.
Eckhart Tolle is pretty much repackaging meditation practises with a huge dose of new age nonsense. As such, there are certainly the odd kernel of useful stuff in there, but I'd recommend a decent introduction to meditation over Tolle any day.
Tolle’s work and meditative practice are not mutually exclusive nor in conflict with one another. His characterization of the human mind—how we create (mostly unintentionally, through conditioned habits) so much suffering and problems for ourselves—is spot on and very helpful for gaining an understanding of ourselves, imo.
