Mbh 13.16.2c

Brahman is concealed in the cave of the heart. The very ascetics are unable to behold or know Him.[80] Thou art that puissant deity who is the doer of everything and whose face is turned towards every direction. Thou art the Soul of all things, thou seest all things, thou pervadest all things, and thou knowest all things. Thou makest a body for thyself, and bearest that body. Thou art an embodied Being. Thou enjoyest a body, and thou art the refuge of all embodied creatures. Thou art the creator of the life-breaths, thou possessest the life-breaths, thou art one that is endued with life-breaths, thou art the giver of the life-breaths, and thou art the refuge of all beings endued with life-breaths. Thou art that Adhyatma which is the refuge of all righteous persons that are devoted to Yoga-meditation and conversant with the Soul and that are solicitous of avoiding rebirth. Verily, thou art that Supreme Lord who is identical with that refuge. Thou art the giver unto all creatures of whatever ends become theirs, fraught with happiness or misery. Thou art he that ordains all created beings to birth and death. Thou art the puissant Lord who grants success to Rishis crowned with success in respect of the fruition of their wishes. Having created all the worlds beginning with Bhu, together with all the denizens of heaven, that upholdest and cherishest them all, distributing thyself into thy well-known forms numbering Eight.[81] From thee flows everything. Upon thee rests all things. All things, again, disappear in thee. Thou art the sole object that is Eternal. Thou art that region of Truth which is sought by the righteous and regarded by them as the highest. Thou art that cessation of individual existence which Yogins seek. Thou art that Oneness which is sought by persons conversant with the soul. Brahma and the Siddhas expounding the mantras have concealed thee in a cave for preventing the deities and Asuras and human beings from beholding thee.
