Madhvacharya's Dvaita Vedanta and translation of Sarvamoola containing Bhagavad Gita, Upanishads, and Brahmasutra.

अष्टपत्रे तु हृत्पद्मे मध्ये सूर्येन्दुवह्निगम्। पीठं तत्पद्ममध्यस्थं नारायणमनामयम् ॥७॥

aṣṭapatrē tu hr̥tpadmē madhyē sūryēnduvahnigam। pīṭhaṁ tatpadmamadhyasthaṁ nārāyaṇamanāmayam ॥7॥

In the eight petal lotus heart of the body is located the solar system, lunar system, and the fire system. One should meditate on Nārāyaṇa who is at the center of these systems.

बहुचित्रजगद्बहुधाकरणात् परशक्तिरनन्तगुणः परमः ।
सुखरूपममुष्य पदं परमं स्मरतस्तु भविष्यति तत्सततम् ॥
"The one who has created this variegated vast universe with varied forms has infinite power and is of infinite auspicious qualities. He certainly bestows the highest state of bliss to those who meditate on his ever happy essence." -Dwādasha stōtra 4.3
