यदग्रे चानुबन्धे च सुखं मोहनमात्मन: |

निद्रालस्यप्रमादोत्थं तत्तामसमुदाहृतम् ||

yad agre chānubandhe cha sukhaṁ mohanam ātmanaḥ
nidrālasya-pramādotthaṁ tat tāmasam udāhṛitam



जो सुख भोगकाल में तथा परिणाम में भी आत्मा को मोहित करने वाला है, वह निद्रा, आलस्य और प्रमाद से उत्पन्न सुख तामस कहा गया है॥


That happiness which covers the nature of the self from beginning to end, and which is derived from sleep, indolence, and negligence, is said to be in the mode of ignorance.


English Translation Of Sri Shankaracharya’s Sanskrit Commentary By Swami Gambirananda

18.39 That joy is udahrtam, said to be; tamasam, born of tamas; yat, which; both agre, in the beginning; ca, and; anubandhe, in the seel, after the end (of enjoyment); is mohanam, delusive; atmanah, to oneself; and nidra-alasya-pramada-uttham, arises from sleep, laziness and inadvertence.

Therefore, now is begun a verse in order to conclude this section [The section showing that all things in the whole of creation are under the influence of the three gunas.].
