Maṇṭreśvara opens with the navagraha — their physical forms (varṇa, jāti, deha), guṇa (sattva / rajas / tamas), elements (tattva), and dignified placements. The chapter is the operating dictionary for every subsequent phala-statement: when Sūrya is referenced later, this chapter defines what Sūrya means.
