Teaching others is best done with subtlety, explaining in such a way that the mind opens because the heart understood.
Aim to inspire, rather than teach. My love for those I teach will do that; my love for God will do that to the extent that I am soul conscious when teaching so others will have this experience.
Never force anyone to make spiritual effort. When the mind opens, this happens naturally.
Avoid making comparisons. It creates loss of hope.
Harbour no ill will, and never try to score a point.
Be like the parent whose love for the child is what is making him grow.
