Why also did the gods and the Asuras in days of old kill each other in battle? If it is Time that begets happiness and misery and birth and death, why do physicians then seek to administer medicines to the sick? If it is Time that is shaping the course of everything, what need is thereof medicines,
कस्माद् देवासुराः पूर्वमन्योन्यमभिजन्निरे। यदि कालेन निर्याणं सुखं दुःखं भवाभवौ॥ भिषजो भैषजं कर्तुं कस्मादिच्छन्ति रोगिणः। यदि कालेन पच्यन्ते भेषजैः किं प्रयोजनम्॥
