The danger in associating with kings arises from the fact that when kings enter upon the scene, and the spell of their influence gains strength, becoming like a great lamp, the person who keeps company with them, claims their friendship, and accepts money from them will inevitably speak in accordance with their desires. That person will listen to the kings’ mundane views with the utmost attention, and will not be able to deny them.
That is where the danger lies, it leads to a fading respect for the true source. When you cultivate the interest of kings, that other interest which is fundamental to the spiritual life becomes a stranger to you. The more you proceed down the path of kings, the more that direction where the Beloved dwells becomes lost.
