The Power of Faith in Spiritual Work
Perception of Pleasure Is Dependent on the Desire for Pleasure
The most important determinant of the perception of pleasure is the thirst for pleasure, which in Kabbalah is known as a “vessel.” The size of the vessel is determined by the degree to which one feels the need for the lack of pleasure.
For this reason, if two separate vessel-people receive the same pleasure, one will receive a feeling of absolute satiation, while the other will feel no sense of possessing anything and, thus, be very depressed.
