In Section 42 of the Hadiqat al-Haqiqah, Sanai employs the architectural and domestic allegory of the internal house thief (dozd-e khāneh) to represent the nafs (the lower soul or ego). Sanai contrasts an external thief, who can only steal superficial, minor household items, with the internal thief, who is far more dangerous because they reside within the house and can plunder the seeker's most precious spiritual assets—their heart (del) and faith (din). While the individual feels secure because their visible possessions seem intact, this internal thief quietly drains the hidden spiritual treasury. Sanai warns that harboring the nafs is like sleeping while a leopard and a mouse coexist within, leaving the seeker completely vulnerable to the deceptive machinations of Satan.
