यावान्वा अयमाकाशस्तावानेषोऽन्तर्हृदय आकाश उभे अस्मिन्द्यावापृथिवी अन्तरेव समाहिते उभावग्निश्च वायुश्च सूर्याचन्द्रमसावुभौ विद्युन्नक्षत्राणि यच्चास्येहास्ति यच्च नास्ति सर्वं तदस्मिन्समाहितमिति ॥ ३ ॥
In plain words
As vast as this external space is, so vast is the space within the heart. Both heaven and earth are held right within it, along with fire and wind, sun and moon, lightning and the stars. Whatever belongs to you here in this world, and whatever does not—all of it is gathered within this inner expanse.
Close to the Sanskrit
As great as this space indeed is, so great is this space within the heart. Both heaven and earth are contained right within it; both fire and wind, sun and moon both, lightning and constellations, and whatever belongs to this here and whatever does not—all that is contained in this.
