B.G 3.22
na mē pārthāsti kartavyaṁ triṣu lōkēṣu kiñcana। nānavāptamavāptavyaṁ varta ēva ca karmaṇi ॥22॥
O Partha, surely, there exists no responsibilities in the three worlds for me, nothing un-attained nor to be gained; Yet I continue performing my actions.
Gīta Tātparya 3.22
Other testimonial also shows - Lord Vishnu, being of the nature of supreme bliss, with his very nature, acts, and performs all actions. Hence, dedicate all actions to Lord Vishnu.
"mamaiva kēvalaṁ nāsti kēnāpyarthaḥ tathāpyaham। karmakr̥t lōkarakṣāyai tasmāt kurvīta matparaḥ॥"
"Only I exclusively have no purpose to be served. Even then, I perform duties to protect the world. Therefore, perform duties dedicating to me."
iti kr̥ṣṇasaṁhitāyām।
-as stated in Krishna Samhita.
"rakṣayā vā'tha sr̥ṣṭyā vā saṁhr̥tyādērna tu kvacit। arthō viṣṇōstathāpyēṣa svabhāvāt sarvakarmakr̥t॥ mattō nr̥ttādikaṁ yadvat kuryāt sukhaviśēṣataḥ। paramānandarūpatvāt kuryād viṣṇuḥ tathaiva tu॥"
"The activities such as creation, protection, and destruction of the universe mean little and serves no purpose for Him. Even then, lord Vishnu, by his innate nature, does all activities similar to the way dance gives me special joy. Lord Vishnu, being of the nature of supreme bliss, acts indeed similarly."
iti barkaśrutiḥ ॥22॥
- thus states Barka testimonial (said by lord Rudra).
