In plain words
The Self, the master, creates for the world neither agency nor the things people make, nor the connection between action and its fruit; rather, Svabhāva operates.
Word for word
The master creates neither agency nor the things made for the world, nor the connection with the fruit of action; but [one's own] nature operates.

किञ्च—
न कर्तृत्वं स्वतः कुरु इति नापि कर्माणि रथघटप्रासादादीनि ईप्सिततमानि लोकस्य सृजति उत्पादयति प्रभुः आत्मा । नापि रथादि कृतवतः तत्फलेन संयोगं न कर्मफलसंयोगम् । यदि किञ्चिदपि स्वतः न करोति न कारयति च देही, कः तर्हि कुर्वन् कारयंश्च प्रवर्तते इति, उच्यते — स्वभावस्तु स्वो भावः स्वभावः अविद्यालक्षणा प्रकृतिः माया प्रवर्तते ‘दैवी हि’(भ. गी. ७ । १४) इत्यादिना वक्ष्यमाणा ॥ १४ ॥
In plain words
And there is more—
The Self, of itself, creates no agency; nor does the Lord create actions, meaning chariots, pots, palaces and all the things the world most craves; 'creates' means produces, and 'the Lord' means the Self. Nor, for one who has made a chariot or the like, does the Self create the link to its fruit — the connection between action and result. So if the embodied self really does nothing and causes nothing on its own, what is it that goes on acting and causing action? Here's the answer: it's 'own-nature' — a being's own inherent nature — that is, primal Nature marked by ignorance, in other words māyā, that does the functioning. This will be explained further later, in the passage beginning, 'divine indeed...'

And what more—
'Not agency' [of itself does the Self create] — 'nor actions' [does the Lord create], [i.e.] chariots, pots, palaces, and the like, the most desired [things] of the world; 'creates,' produces, 'the Lord,' [i.e.] the Self. 'Nor,' for one who has made chariots and the like, 'the connection with their fruit,' [i.e.] the connection of action and its fruit. If the embodied self does not, of himself, do or cause [others] to do anything at all, then what functions, acting and causing to act? It is answered: 'own nature,' however — one's own being is 'own-nature' — [i.e.] primal Nature characterized by ignorance, [i.e.] māyā, functions — yet to be described in the passage beginning, 'divine indeed...' (Gītā 7.14).
