Mantra 9

अविद्यायां बहुधा वर्तमाना वयं कृतार्था इत्यभिमन्यन्ति बालाः ।यत्कर्मिणो न प्रवेदयन्ति रागात् तेनातुराः क्षीणलोकाश्च्यवन्ते ॥ ९ ॥

In plain words

Dwelling in many ways within Avidyā, the childish imagine, ‘We have accomplished our purpose.’ Because the performers of Karma, driven by Rāga, do not truly understand, they fall away afflicted when their worlds are exhausted.
