The joy that, both in the beginning and at the end, distracts from the soul,
Arising from sleep, sloth, negligence, that exemplifies tamas.
Source: Milind S. Pandit
Pleasure that deludes a person in the beginning and in the end; which comes from sleep, laziness, and confusion; such pleasure is called Taamasika (pleasure).
And that happiness which is blind to self-realization, which is delusion from beginning to end and which arises from sleep, laziness and illusion is said to be of the nature of ignorance.
