The acquirement of spiritual wisdom does not necessarily prevent us from making worldly mistakes; but because it develops the qualities that will prevent them, and because it takes to heart the lessons of experience, humbly and receptively, it does reduce the frequency of those mistakes.
By teaching in silence and by bringing down the force of the Light, you are asking for a very deep and very intense surrender. What is surrender?
To offer everything to the Divine is surrender. To give our live our lives to the Divine is surrender. Simplicity is surrender...Always remember, no matter how great we are, that there is something greater -- the Divine. To be humble is surrender...Whatever you do, give it to God with a grateful and humble heart.
