Quote in context:
"A certain satisfaction with our abilities can be skilful, but the pride that suggests to us we have more knowledge or ability than other people serves only to leave us even more separate from others than before. If we relate in this way, the language of the heart is suppressed because we are coming only from the logical intellect which is often devoid of the qualities of the heart. This is why spiritual pride impedes those who have acquired a lot of knowledge. Wisdom and knowledge are not the same, and speech dominated by intellectual knowledge hardly ever contains wisdom. Knowledge is helpful only if it can be put into action. Think a bit less and act a bit more! Teresa of Avila said, ‘Stop thinking so much; start loving more!’"
