युद्धजयार्णवः (योगाः नक्षत्राणि)
वह्निभिश्चाऽऽहतं कृत्वा रूपं तत्रैव निक्षिपेत् ।स्पन्दनं नाड्याः पलानि सप्राणस्पन्दनं पुनः ॥ ४ ॥
In the full Agni Purana this is chapter 123, verse 4.
Multiply it by 3 and add 1 there. This gives the throbs of the breath and the palas (24-second units). Then again, the throbs together with the breath.
Simple meaning: Multiply by 3 and add 1. This counts the throbs of the breath and the small time units.
अनेनैव तु मानेन उदयन्ति दिने दिने ।
They rise day after day by the same measure. Three beats make a breath.
षष्टिभिश्च पलैर्लिप्ता लिप्ताषष्टिस्त्वहर्निशम् ।
Sixty palas make a lipta, and sixty liptas a day and night. Rising goes through five life stages.
मृत्युर्येनोदयस्तेन चास्तमेकादशांशकैः ।
Death is the fifth stage. Defeat comes when the clan group enters, and the fifth stage brings death.
