My opinion in endless forests of opinion: “Falling into emptiness” (entering into a state where one sees that all is empty and trying to remain in or return to that temporary state) is not Buddhism or Buddhist practice. As you say, this is an oft repeated caution in orthodox Buddhism which does not contradict at all "Therefore, Ananda, you should train yourselves: 'We will enter & remain in the emptiness that is pure, superior, & unsurpassed.” in the fuller context of the historical Buddha's teachings or the following two thousand years of commentary and teaching in the mainstream traditions. Falling into any temporary state or experience and staying there or wallowing in it is a danger. Adhering to Emptiness or non-emptiness is a fundamental mistake.[james] wrote: ↑Wed Jun 26, 2019 1:03 am"Therefore, Ananda, you should train yourselves: 'We will enter & remain in the emptiness that is pure, superior, & unsurpassed.”
What do you refer to, Caodemarte, with “falling into emptiness”? I know that it is an oft repeated caution. What is the danger exactly? Is the emptiness that one might fall into, as opposed to enter, a false emptiness? If one has the capacity and good conditions to recognize, enter and dwell in emptiness, can that be false do you think?
Mahayana Buddhism repeatedly stresses that as long as you see a difference between emptiness and non-emptiness, have a view that enlightenment or emptiness is something one falls into or can enter into, believe that the view of samsara (here phenomenon) and seeing the dharma (here noumenon) are two different views or things (as in certain optical illusions where one can alternate seeing a woman's profile or a cup, but not at the same time) that one alternates, may or may not be helpful, even wholesome states, stages, or steps at certain points, but just that - mere states. They are also traps if one is caught there. One must drop all this, and not be caught by anything.
For a clear Zen reference look at the 10 Oxherding pictures. If one stops at the Enso/Won/Big Empty Circle picture one is making "enlightenment" itself a trap, just another state. Go all the way! Enlightenment or Emptiness is ordinary life. After all, "Nothing can move you further or closer to the Dharma" (Dahhui Puje, if menory serves, from The Letters of Chan Master Dahui Pujue, Broughton). Seeking or staying in some marvelous state will not do it either (in fact, it is part of the dis-ease or dukkha).
If you really enter ordinary life or if you really enter Emptiness or anything else, you will go through them and see how one abides in non-abiding or non-abides in abiding. Don’t attach to anything, including emptiness. That is what entering and abiding in true emptiness or “ordinary life” really is.
This reminds me of the old koan "All returns to the One. What doe the One return to?" Staying in the One or emptiness or anything else is not correct practice in Buddhism as I understand it.
