Ādi-parva Adhyāya 97: Satyavatī’s appeal and Bhīṣma’s reaffirmation of satya
संध्यां वसिष्ठमासीनं तमत्यभिसूता: पुरा । तेन कोपाद् वयं शप्ता योनौ सम्भवतेति ह
sandhyāṃ vasiṣṭham āsīnaṃ tam atyabhisūtāḥ purā | tena kopād vayaṃ śaptā yonau sambhavateti ha ||
Vaiśampāyana said: Formerly, when the sage Vasiṣṭha was seated at the time of twilight worship, we behaved with grave impropriety toward him. Because of that, in anger he cursed us, saying, ‘You shall be born from a womb.’
