“When you admonish your friend, let it be without bitterness; when you chide him, let it be without reproach; when you praise him, let it be with worthy purpose, and for just causes, and in friendly measures; too much of that is flattery, to little is envy; if you do it justly, you teach him true measures: but when others praise him, rejoice though they praise not thee, and remember that if thou esteemest his praise to be thy disparagement, thou art envious, but neither just nor kind.” – Jeremy Taylor, “A Discourse on Friendship”
Purity of heart is the greatest treasure any person can bring to a friendship. No other tool, skill or state of being can bring a healing current as effectively, for in purity of heart is corrective equanimity, radiant selflessness and compassionate intercession.
A pure heart is an untroubled heart. The suggestion that you “let not your heart be troubled,” therefore, is the key to unlocking all the excellencies of friendship.
