विद्यत इति अनन्दः; 'यो वै भूमा तत्सुखं नाल्पे सुखमस्ति' इति श्रुतेः ।सत्या धर्मज्ञानादयोऽस्येति सत्यधर्मा ।त्रयो विक्रमास्त्रिषु लोकेषु क्रान्ता यस्य सः त्रिविक्रमः; 'त्रीणि पदा विचक्रमे' इति श्रुतेः; त्रयो लोकाः क्रान्ता येनेति वा त्रिविक्रमः ।'त्रिरित्येव त्रयो लोकाः कीर्तिता मुनिसत्तमैः ।क्रमते तांस्त्रिधा सर्वांस्त्रिविक्रमोऽसि जनार्दन' इति हरिवंशे ॥
In plain words
Ananda is bliss itself, as the scripture declares: 'The infinite alone is joy; there is no joy in the finite.' Satyadharma is the Lord whose attributes—beginning with supreme knowledge—are entirely true. Trivikrama is the one who has spanned the three worlds with his three mighty strides, according to the Vedic text: 'He strode across the universe in three steps,' or because the three worlds are traversed by him. As the Harivamsa proclaims: 'The sages declare the three worlds to be none other than these; you traverse them all in a threefold way, O Janardana, for you are Trivikrama.'
Close to the Sanskrit
Ananda is bliss, on the authority of the Sruti passage: 'That indeed is the infinite, that is happiness, there is no happiness in the small.' Satyadharma is one whose true nature consists of righteousness, knowledge, and the like. Trivikrama is one by whom three strides have been spanned across the three worlds, on the authority of the Sruti: 'He strode across in three steps'; or Trivikrama is one by whom the three worlds are spanned. As stated in the Harivamsha: 'The three worlds are indeed declared by the best of sages to be the three; you span all of them in three ways, O Janardana, you are Trivikrama.'
