I relate to that quote's perspective. I think it's fine to research anything and learn about anything, and it doesn't mean that we have to become attached to it.
As an example, in the past I researched Hinduism to an extent just to see what it was all about. I realized that it was a religion which I didn't really like actually, though I did like certain aspects of it. So now when I cross paths with a Hindu, I have stuff to talk to them about, I can say, "I love the threefold philosophy you have about the Creator being Creator Preserver and Destroyer, and how the beginning of the Gita starts out on a battlefield, it really sets the story. I can talk like that for a few minutes, sharing what I like about it with him, and then I can go my own way and not think of the gita again for years, because actually I reject it as a whole. The Hindu will have felt good that someone likes his favorite story, yet I will not be someone who likes his favorite story. The concept of their being millions of gods is ridiculous to me and Hinduism strikes me as an ignorant religion focusing far too much on self (achieving the "godhead" and other somesuchnonsense).
I guess my point is that if we learn how to be detached and distance ourselves from anything in our presence, such as something to learn about, then we can learn about it with an open mind, without getting lost because we attached to something too quickly which wasn't wholesome. Meister Eckhart said that detachment is more important than even love. I disagreed at first but now I think I get his point. Detachment is more important than love if the way that people are showing "love" is by being too attached to the point of harming you. Like the parents who freak out because they smell pot coming from their 16-year old's bedroom, so they start placing video cameras around the whole house out of "love". I think it would be better to be detached than to act like that as a parent. After all, life will teach a person better than that can.
I think it's important to have an open mind, but not too much, because that would be attachment. Too often an open mind is an empty mind. It's probably good to have an open mind but to not just accept anything that comes our way, as that would be the attachment mind. This is something I've thought about a lot, so I hope I nailed the point. By the way, I love the "it could be worse" quote you have there, that is going to put a smile on my face all week I assure.
