Hmm I don't recall that at the moment, but I do remember him saying something about the Buddha did not talk about the "present moment", does anyone remember that one?
Burn up what's before,
and have nothing for after.
If you don't grasp
at what's in between,
you will go about, calm.

I suspect this is what he would be getting at in that talk you are looking for though:
"What this means is that, as a meditator, you can't treat everything in the present moment in the same way. You can't simply stay non-reactive, or simply accept everything that comes. If moments of stillness and ease arise in the mind, you can't just note them and let them pass. You should learn to develop them into jhana"http://www.accesstoinsight.org/lib/auth ... gling.html
