Buddha-carita, or The Life of Buddha - 148
ityarāḍaḥ kumārasya māhātmyādeva coditaḥ |
sakṣipta kathayā cakre svasya śāstrasya niścayam || 12.15
15. Arāḍa, thus impelled by the noble nature of the prince, declared in a concise form
the tenets of his doctrine:
śrūyatāmayamasmāka siddhātaḥ śṇvatā vara |
yathā bhavati sasāro yathā vai parivartate || 12.16
16. ‘O best of hearers, hear this our firmly-settled theory, how our mortal existence
arises and how it revolves.
praktiśca vikāraśca janma mtyurjaraiva ca |
tattāvatsattvamityukta sthirasattva parehi naḥ || 12.17
17. “The evolvent" and "the evolute," birth, old age, and death, — know that this has
been called the reality by us; do thou receive our words, O thou who art stedfast in thy
nature.
tatra tu praktirnāma viddhi praktikovida |
paca bhūtānyahakāra buddhimavyaktameva ca || 12.18
18. ‘But know, O thou who art deep in the search into the nature of things, that the
five elements, 1 egoism, intellect, and "the unmanifested" are the "evolvents;"
vikāra iti buddhi tu viṣayānidriyāṇi ca |
pāṇipāda ca vāda ca pāyūpastha tathā manaḥ || 12.19
19. ‘But know that the "evolutes" consist of intellect, external objects, 2 the senses, and
the hands, feet, voice, anus, and generative organ, and also the mind.
asya kṣetrasya vijñānāt kṣetrajña iti sajñi ca |
kṣetrajña iti cātmāna kathayatyātmacitakāḥ || 12.20
20. ‘There is also a something which bears the name kṣetrajña, from its knowledge of
this "field" (kṣetra or the body); and those who investigate the soul call the soul
kṣetrajña.
saśiṣyaḥ kapilaśceha pratibuddha iti smtiḥ |
saputraḥ pratibuddhaśca prajāpatirihocyate || 12.21
21. ‘Kapila with his disciple became the illuminated, — such is the tradition; and he, as
the illuminated, with his son is now called here Prajāpati.
1 These are the tanmātrāṇi or subtile elements.
2 Viṣayān, corresponding to the gross elelments. The intellect buddhi is both an evolver and an
evolute.
