O king of the celestials, Vritra had practised, for full sixty thousand years, the severest penances for acquiring strength. Brahma gave him the boons he had prayed for, viz., the greatness that belongs to Yogins, large powers of illusion, enough of might, and superabundant energy.
अनेन हि तपस्तप्तं बलार्थममराधिप। षष्टिं वर्षसहस्राणि ब्रह्मा चास्मै वरं ददौ॥ महत्त्वं योगिनां चैव महामायत्वमेव च। महाबलत्वं च तथा तेजश्चाम्यं सुरेश्वर।॥
