2.16

नासतो विद्यते भावो नाभावो विद्यते सतः ।
उभयोरपि दृष्टोऽन्तस्त्वनयोस्तत्त्वदर्शिभिः ॥

nāsato vidyate bhāvo nābhāvo vidyate sataḥ
ubhayor api dṛṣṭo 'ntas tv anayos tattvadarśibhiḥ

Kṛṣṇa (कृष्ण) continues, and this verse is the hinge of the stretch.

The verse

Of what is not, no coming-to-be is found, and of what is, no ceasing-to-be is found, and the end of both has been seen by those who see what is so.

नेपालीमा

जे छैन त्यसको उत्पत्ति पाइँदैन, र जे छ त्यसको नाश पाइँदैन। दुवैको अन्त्य जे हो त्यो देख्नेहरूले देखेका छन्।

Where it sits

What passes has no lasting bhāva (भाव), and what is has no abhāva (अभाव): he has said sat (सत्) and asat (असत्), and that the end of each has been seen. The grief treats the dying as if the real ceased.

The phrases

na asataḥ vidyate bhāvaḥ (न असतः विद्यते भावः) is the first finding. Of what is not, no coming-to-be is found. न + असतः na + asataḥ is nāsataḥ (नासतः), and asataḥ (असतः) before the voiced v (व्) is recited nāsato (नासतो). bhāvaḥ (भावः) before na (न) is bhāvo (भावो).

na abhāvaḥ vidyate sataḥ (न अभावः विद्यते सतः) is the second. Of what is, no ceasing-to-be is found. न + अभावः na + abhāvaḥ is nābhāvaḥ (नाभावः), recited nābhāvo (नाभावो) before vidyate (विद्यते).

ubhayoḥ api dṛṣṭaḥ antaḥ tu anayoḥ tattvadarśibhiḥ (उभयोः अपि दृष्टः अन्तः तु अनयोः तत्त्वदर्शिभिः) is who has seen the end of both. उभयोः + अपि ubhayoḥ + api is उभयोर् अपि ubhayor api. दृष्टः + अन्तः dṛṣṭaḥ + antaḥ is dṛṣṭo 'ntaḥ (दृष्टोऽन्तः). अन्तः + तु + अनयोः antaḥ + tu + anayoḥ is अन्तस् तु अनयोः antas tv anayoḥ, and तु + अनयोः tu + anayoḥ is tv anayoḥ (त्वनयोः). The seers are instrumental: the end is seen by them.

Sanskrit in this line

दृष्टः + अन्तः dṛṣṭaḥ + antaḥ is recited dṛṣṭo 'ntaḥ (दृष्टोऽन्तः). The avagraha is the dropped a (अ) of antaḥ (अन्तः), "the end." Lose the avagraha and you lose the thing that was seen. अः + अ aḥ + a becomes o (ओ) plus silence where a (अ) was. The genitives asataḥ (असतः) and sataḥ (सतः) are the other half of the same lesson: "of what is not," "of what is," and vidyate (विद्यते) says what is found, or not found, of each.

Say it back

What is not found of each, and who has seen the end. antaḥ (अन्तः) has to survive the avagraha.
