ॐ सर्वे भवन्तु सुखिनः सर्वे सन्तु निरामयाः। सर्वे भद्राणि पश्यन्तु मा कश्चिद्दुःखभाग्भवेत्॥
oṁ sarve bhavantu sukhinaḥ sarve santu nirāmayāḥ; sarve bhadrāṇi paśyantu mā kaścid duḥkha-bhāg bhavet
May all be happy, may all be free from illness, may all see what is good, and may no one suffer.
“Hold a wish for the well-being of all beings today.”
