I found this portion of the collect from the 1962 Roman Breviary for today's feast of Pentecost to be quite inspiring and a good meditation:
"Give us the grace, under His divine inspiration, to have a sense of the true and a taste for the good..."
Having a sense of the true, and a taste for the good. It's a pertinent meditation upon the Christian life in any age, but a particularly good reminder in an age of increasing relativism and indifferentism. Beautiful.
(More on the topic of Pentecost, Father Zuhlsdorf details a beautiful custom done at the Pantheon in Rome on this feast.)
