My interpretation of this verse is that: Vajrayana’s “fast path to Nibbana in this life” is completely ignorant of what the Buddha said.
Perhaps you can give more context of the sutta you are talking about, and what practice you know about that does such false fast tracks as a practice. The post does not make sense.
