There is no point in begging for water with a leaky cup. Water thereby gained is immediately lost again. First fix the cup, then beg for water.
So also with the glimpses and gleanings and intimations from Elsewhere. They won't be retained in a perforated vessel. And if they are not retained, then they cannot do you any good. Moral fitness and intellectual discrimination are necessary for their recognition, proper evaluation, retention if judged salutary, and existential implementation. If you can't act right or think straight, then mystical, religious, and paranormal vouchsafings, whether they come 'out of the blue' or as a result of formal spiritual practices, may do more harm than good. They may inflate the ego or lead it into the dark regions of the occult.
You are sliding down a mountain towards certain death. Your only hope is to grab the rope that is thrown to you. Will you refuse to do so because the rope might break? Will you first inquire into the reliability of the rope or the credibility of the assurances of the one who would be your savior?
A man planted a tree to shade his house from the desert sun. The tree, a palo verde, grew like a weed and was soon taller than the house. The house became envious, feeling diminished by the tree’s stature. The house said to the tree: "How dare you outstrip me, you who were once so puny! I towered above you, but you have made me small."
The tree replied to the house: "Why, Mr. House, do you begrudge me the natural unfolding of my potentiality, especially when I provide you with cooling shade? I have not made you small. It is not in my power to add or subtract one cubit from your stature. The change you have ‘undergone’ is a mere Cambridge change. You have gone from being taller than me to being shorter; but this implies no real change in you: all the real change is in me. What’s more, the real change in me accrues to your benefit. As I rise and spread my branches, you are sheltered and cooled. The real change in me causes a real change in you in respect of temperature."
Heed well this parable, my brothers and sisters. When your neighbor outstrips you in health and wealth, in virtue and vigor, in blog posts or the length of his curriculum vitae – hate him not. For his successes, which are real changes in him, need induce no real changes in you. His advance diminishes you not one iota. Indeed, his real changes work to your benefit. You will not have to tend him in sickness, nor loan him money; your tax dollars will not be used to subsidize his dissoluteness; the more hits his weblog receives, the more yours will receive; and the longer his CV the better and more helpful a colleague he is likely to be.
