The instruction is in the title, and it is not a comfortable one. Resist Nothing asks for the opposite of what most people do when life turns awkward, and Kim Eng puts that proposition at the front rather than building up to it over several chapters.
Just over two hours, filed across wellbeing, personal development and spirituality, indicates something closer to a teaching than to a book in the conventional sense. Material of this kind is meant to be practised rather than merely finished, which is why the running time matters far less than how often you return to it.
Kim Eng also delivers it, and in contemplative work the voice is not a delivery mechanism but part of the instruction: the pace of the speaking sets the pace of the listening.
