It may seem crazy, but if there is just a tiny possibility that there are other dimensions, worlds of ecstasy and unspeakable love, then we should do our best to understand how to get there.
Considering that our physical life has an inevitable deadline, perhaps the craziest thing we can do is to keep ignoring every alternative to our reality.
At the same time, an equally insane thing is not to value, love and honor what we have encountered so far in this world. This world could also be the only possible world. The people and places we experience may be the only possible people and places, no matter where and when we go.
