I've carried a copy of 365 Tao with me since the early 1990s ('93, I think?). There's something magical about it—for me it's pulled the veil of the universe back a bit and I can see how it's conspiring in our favor (pronoia) if we're awake. In terms of serendipity, I think the passages are so objective that we glean from them what we need at the specific time we're reading them each year. This is the true value of a daily reader, I think. It reminds of me of that Heraclitus quote, no man ever steps in the same river twice. : ) That's kind of you to say, thank you!
