These two words refer to two aspects of idol worship. Idol Worshipping refers not only to bowing down before statues and icons. Idol worshipping includes any material possession or external situation that controls our emotions and behavior or that motivates us in any way. When any of these influences determine our degree of contentment and joy in life, then we have surrendered control and severed our connection to the Light, the true source of all fulfillment. Often, our negative tendencies lead us to become worshippers of wealth, or disciples of our own egos.
We can remove the power and allure of the "idols" that control us by meditating upon the Hebrew letters.
