The sudden/gradual, immanence/distinction tensions have gone on for a long long time....explored quite brilliantly by Sam Van Schaik (and others, I'm sure). May be less conflicting if one is able to take the pointers, not as a way to be free 'instantly', but as a way of training
That could sound heretical to many who are within a mahamudra lineage/context, and almost certainly isn’t even Buddhist - but for some that sort of view could actually be tremendously helpful and/or enjoyable. The motivation/intention isn’t the same, but that’s fine by me.
