Matsya Purana — Rite of Donating the ‘Sugar Mountain’
चन्द्रतारार्कसंकाशम् अधिरुह्यानुजीविभिः सहैव यानमातिष्ठेत् तत्र विष्णुप्रचोदितः //
candratārārkasaṃkāśam adhiruhyānujīvibhiḥ sahaiva yānamātiṣṭhet tatra viṣṇupracoditaḥ //
Urged on by Viṣṇu, he should then board the conveyance—shining like the moon, the stars, and the sun—together with his attendants and dependents, and take his place there.
It depicts the practical moment of survival during Pralaya: by Viṣṇu’s command, Manu boards the divinely radiant boat, indicating divine orchestration and protection amid cosmic dissolution.
By emphasizing boarding “together with dependents,” the verse reflects the dharmic duty of a leader/householder to protect and carry along those under their care (retainers, followers, family) in times of danger, not seeking salvation alone.
While not a Vāstu rule, it has ritual-symbolic significance: the “vehicle/boat” functions as a divinely sanctioned refuge (a sacred conveyance), a motif often echoed in later ritual storytelling and iconography of Matsya guiding beings across catastrophe.
