अग्निनिचयः (Agninichaya) / The Accumulation of Sacred Fire & the Classification of Pitṛs by Time-Order
या तु देवी सती पूर्वमासीत्पश्चादुमाभवत् / सदा पत्नी भवस्यैषा न तया मुच्यते भवः
yā tu devī satī pūrvamāsītpaścādumābhavat / sadā patnī bhavasyaiṣā na tayā mucyate bhavaḥ
The Goddess who was Satī before became Umā thereafter; she is ever the wife of Bhava (Śiva), and Bhava is never parted from her.
