Buddha-carita, or The Life of Buddha - 163
115. ‘Inasmuch as lines of birds fluttering in the sky offer thee reverential salutation,
O lotus-eyed one, and inasmuch as gentle breezes blow in the sky, thou shalt certainly
to-day become the Buddha.’
tato bhujagapravareṇa sastutastṇānyupādāya śucīni lāvakāt |
ktapratijño niṣasāda bodhaye mahātarormūlamupāśritaḥ śuceḥ || 12.116 (12.119)
116. Being thus praised by the best of serpents, and having taken some pure grass from
a grasscutter, he, having made his resolution, sat down to obtain perfect knowledge at
the foot of the great holy tree.
tataḥ sa paryakamakapyamuttama babadha suptoragabhogapiḍitam |
bhinadmi tāvadbhuvi naitadāsana na yāmi tāvatktaktyatāmiti || 12.117
(12.120)
117. Then he sat down on his hams in a posture, immovably firm and with his limbs
gathered into a mass like a sleeping serpent’s hood, exclaiming, ‘I will not rise from
this position on the earth until 1 I have obtained my utmost aim.’
tato yayurmudamatulā divaukaso vavāsire na mgaganā na pakṣiṇaḥ |
na sasvanurvanataravo ’nilāhatāḥ ktāsane bhagavati niścalātmani || 12.118
(12.121)
118. Then the dwellers in heaven burst into unequalled joy; the herds of beasts and the
birds uttered no cry; the trees moved by the wind made no sound, when the holy one
took his seat firm in his resolve.
