Don't opine on things you are not familiar with, least understand or still understanding. Listening instead with an open and unprejudiced Mind, will teach us more than speaking unwarranted BS.
Alas! We are so obsessed with our own Words, that we don't mind sacrificing our Silence and Wisdom, on the altar of Self-Aggrandisement.
The ones who can control their Tongue and Tail***, have successfully controlled and salvaged a major part of their Spiritual undoing.
