Īśā.Bhāshya 01

This universe is incapable of engaging in action on its own, Hence it belongs to the Lord. Therefore, one should enjoy only what is given.

ईशस्य आवासयोग्यम् ईशावास्यम्। जगत्यां प्रकृतौ। तेन ईशेन। त्यक्तेन दत्तेन। भुञ्जीथाः।

The word 'īśāvāsyam', i.e. the lord's, is that which is fit for the dwelling of the Lord. The word 'jagatyām' means 'prakrti', i.e. the insentient, or the presiding deity of the insentient. The word 'tena', i.e. by the Lord. The word 'tyaktena' is used to mean 'given by', to enjoy.

"स्वतः प्रवृत्याशक्तत्वात् ईशावास्यमिदं जगत्। प्रवृत्तये प्रकृतिगं यस्मात्सप्रकृतीश्वरः। तदधीनप्रवृत्तित्वा तदीयं सर्वमेव यत्। तद्दत्तेनैव भुञ्जीथाः अतो नान्यं प्रयाचयेत्॥"

"Because this universe is incapable of engaging in action on its own, it belongs to the Lord. The tendency to act is dependent on insentient Prakrti and He is the lord of that insentient Prakrti as well. Indeed, including the tendency to act, everything is under His control only. Therefore, one should enjoy only what is given by Him and not covet from others."
