Well, my understanding is that according to Vajrayana things are different now, and that kind of approach is not as effective anymore. Maybe you don't agree, but I think they might have a point. All of those movements you mention are quite ancient aren't they?
In the Heian period plenty of people sincerely believed this was the Dharma Ending Age, so liberation was no longer possible. You could best hope for rebirth in the Pure Land. Nobody could become liberated any longer.
I don't accept such beliefs. I don't accept that the Buddha's original practices and teachings are ineffective.
The meaning of the Buddha's teachings are normally self-evident and their implications discussed in Abhidharma and commentary literature, or expressed through Mahāyāna literature at times. Ideas similar to those of the Buddha are found in other traditions which often note the same principles: simple living means less worries in life, a quiet mind leads to internal and external harmony, etc.
