HOW IS THE KARMA OF SLANDERING THE DHARMA CREATED

The misdeed of slandering the Dharma is unconsciously created when one denies or defames the teachings loosely and mindlessly.

Practitioners should not uphold their mind too loosely or leisurely, because that is a habit which will create negative karma once it surfaces. If one creates the karma of slandering the Dharma (under such circumstance), it is too terrifying!
