Do something creative! Especially if you have any experience painting, or doing computer art, or playing a musical instrument. The outdoors is also great (I know, it's February). Writing is also good, as mentioned above. Try to articulate your experience, even if indirectly. Doing something creative is an active way of integrating the experience.
...also mentioned above: reading can be great too. You've had a recent perspective tweak, and you may find yourself marveling at the slightly different ways (or drastically different, possibly) that you digest and interpret what you read.
Share your experience here, in detail, in the experience reports! Writing down the details of your journey during the afterglow will help you remember specifics. Does your new perspective give you any specific new insights? Write those down too!
You can take a very proactive role in the integration process... It's an art in itself.
