In spite of achieving the power to control in all directions and in spite of enjoying all types of dear sense gratification as much as possible, Hiraṇyakaśipu was dissatisfied because instead of controlling his senses he remained their servant.

मूल श्लोकः
स इत्थं निर्जितककुबेकराड् विषयान् प्रियान् । यथोपजोषं भुञ्जानो नातृप्यदजितेन्द्रियः
sa itthaṃ nirjitakakubekarāḍ viṣayān priyān | yathopajoṣaṃ bhuñjāno nātṛpyadajitendriyaḥ
