When I wrote the story ["The Cartographers"], I'd just gone through a breakup with a woman I'd loved dearly. Without this other person in my life, the memories we'd shared often felt like phantoms. Who was this person I once loved? Did she still really exist? The answer, on a metaphysical level, was that this person didn't still exist. She'd gone on to become a different person, an individual with new hopes and dreams which no longer involved me.

In Nepal, I realized a certain part of my spiritual search had come to an end. I wasn't ever going to live in a Himalayan cave (I like electricity and a soft bed way too much), and I sure wasn't going to find enlightenment so easily.

One of my central approaches to writing speculative fiction is to take an absurd situation, which we presently feel is normal, and then push it to an even further absurdity. It's only in this light that we can see the reflection of the disturbing state of our present-day affairs.

While I've always been critical about this peddling of spiritual materialism, it wasn't until I went to Nepal that I came face-to-face with my own spiritual materialism. The thing is, Kathmandu is noisy, and dusty, and crowded, and everywhere you go you see these same Western yoga teachers, hashish-smoking backpackers, and fair-trade shop owners, all seeking the stalls filled with amazing Buddha statues, hand carved mirrors, beautiful yak scarves, and thangka paintings. And everyone is buying stuff!

"Moksha" is really a satire of myself. I've always been interested in Eastern spirituality. I'm particularly interested in enlightenment and the spiritual pursuit to liberate ourselves (I'm a Buddhist at heart). During my teenage years, I imagined I'd end up going to India to become a yogi; study with the last living saints in a cave; give up all my worldly possessions; learn to levitate. And there's still part of me that can see myself "disappearing" for some years at an ashram somewhere.

I'm a big fan of Chris Hedges and Joe Sacco's book Days of Destruction, Days of Revolt, where they visit what they call The Sacrifice Zones of America and report on the current state of our environmental calamity.

I think the future is intrinsically linked with our universal human problems. In fact, it's these very problems, and how we deal with them, which will determine our future.
