api doṣasahasrāṇi yadi putraḥ samācaret ..
prāṇadrohe'pi nirato na mātā pāpamācaret ..
tasmātsatyaṃ mama brūhi mā śāpavaśagā bhava .. 131 .. ..

Even if a son should commit thousands of faults, / even if intent on destroying her life, a mother would not commit a sinful act. / Therefore, speak the truth to me; do not fall under the power of a curse!” 131
