यदग्रे चानुबन्धे च सुखं मोहनमात्मनः।
।।18.39।। जो सुख प्रारम्भ में और परिणाम (अनुबन्ध) में भी आत्मा (मनुष्य) को मोहित करने वाला होता है? वह निद्रा? आलस्य और प्रमाद से उत्पन्न सुख तामस कहा जाता है।।
That sukham or happiness which enthrals the jiva or embodied being both at the beginning and as well at the end even after the habitual, repetitive experience exhibits its true nature of enslavement and bondage to samsara the perpetual cycle of birth and death is affirmed by Lord Krishna as tama guna the mode of ignorance. The word mohanam means delusion and is the obscuration of the true nature of reality. Nidra or slumber denotes unconsciousness which can transpire even while engaging in an act of enjoyment. Alasya is slothfulness, the lassitude which comes from habitually dulled senses and which certainly contributes to dullness of mind. Pramada is inattention to what is required and is connected to dullness of mind. So the delusive nature of nidra, alasya and pramada are all situated firmly in tama guna and along with the characteristics of raja guna are very detrimental to the aspiring jiva.
