I am reading the Tibetan Book of the Dead Chapter 2 page 26, "A prayer for union with the spiritual teacher [entitled], Natural Liberation, without renunciation of the three poisons".
Now in reading this chapter it seems that is a call for union with the fundamental buddha bodies of Reality, Resource, and Emanation.
I find it curious that the chapter EXPLICITLY states what the three poisons are, makes a mention "how needing of compassion ..." are buddha bodies that engage in these poisons and proceeds to give an explicit solution, yet renunciation of the poisons is not asked of the reader in fact the title of the prayer explicitly states they will not be renounced.
Why is it important NOT to renounce these poisons at this stage of prayer? The beginning of the book makes it clear that much will be renounced (including the desire of sympathy) as it merely perpetuates our cyclic existence yet here an explicit effort is being made to acknowledge the poisons but NOT renounce them.
What reason is there for this? At best I can theorize that this has to do with avoiding the type of extreme asceticism that the buddha believed did not allow one to break the cycle, but surely anyone engaging in the poisons described without some renunciation will be trapped all the same.
