With the gaze directed downward, one should know the Heart that abides a span above the navel. That Heart is to be understood as the great abode of the universe—where Pati (Śiva) is realized within the pashu when the pasha of distraction is stilled.
Suta Goswami (narrating the Linga Purana’s teaching to the sages of Naimisharanya)
It shifts linga-upāsanā from only an outer icon to antaryāga: the “heart” is taught as the great āyatana where the devotee contemplates Mahādeva as the indwelling Pati.
Śiva-tattva is implied as the cosmic support present within: the heart-locus is called the universe’s great abode, indicating Pati as immanent while remaining transcendent.
A meditative discipline: lowering the gaze and fixing awareness in the hṛdaya a span above the navel—used in Pāśupata-oriented inner worship to quiet pasha and steady the pashu in Śiva.
