B.G 3.22
न मे पार्थास्ति कर्तव्यं त्रिषु लोकेषु किञ्चन। नानवाप्तमवाप्तव्यं वर्त एव च कर्मणि ॥२२॥
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.
"ममैव केवलं नास्ति केनाप्यर्थः तथाप्यहम्। कर्मकृत् लोकरक्षायै तस्मात् कुर्वीत मत्परः॥"
"Only I exclusively have no purpose to be served. Even then, I perform duties to protect the world. Therefore, perform duties dedicating to me."
इति कृष्णसंहितायाम्।
-as stated in Krishna Samhita.
"रक्षया वाऽथ सृष्ट्या वा संहृत्यादेर्न तु क्वचित्। अर्थो विष्णोस्तथाप्येष स्वभावात् सर्वकर्मकृत्॥ मत्तो नृत्तादिकं यद्वत् कुर्यात् सुखविशेषतः। परमानन्दरूपत्वात् कुर्याद् विष्णुः तथैव तु॥"
"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."
इति बर्कश्रुतिः ॥२२॥
- thus states Barka testimonial (said by lord Rudra).
