Place of the Heart
The noble heart of a human is the center for universal love and is not to be filled with dark thoughts and foul imaginations. Brain and heart are two magnanimous sources of divine power bestowed upon humans, and it is from this gift that all blessings and felicities in human history have come to life.
So, you must never let any wry thoughts get into the mind, and if one was determined to penetrate, you are to evict it as soon as possible. Your noble and unsullied house of mind needs to have a guard that never opens the gates for inappropriate thoughts. It should only let in clean and noble thoughts. The mind might be compared to a beehive. Beehives have dedicated sentinels that inspect those who seek entrance, and they never let in anyone with so little as a stained foot or body. The sentinels do this in order to maintain the unsullied environment of the hive. Only clean, unsullied, active, and efficient bees are accepted in the hive. Are we any less than the bees that carry out such purifications?
