When One attains the position to teach, One should. Depending on the effect of their teachings, when an individual has the capacity to understand something enough to share it with others, it is wise and kind to do so.
The act of teaching, in essence, is an act of love.
It requires willingness and openness to questioning, and One must bow to a better truth when corrected. One must simultaneously play two roles; humble themselves and learn in an ever-changing landscape of knowledge, and responsibly disseminate that knowledge to other anxious open minds and hearts.
Life lessons of patience, fearlessness, generosity, acceptance, and forgiveness–are not easily learned. For they are the teachings that shape the One language that all in this world can universally understand.
