Restraint of the Senses, Non-harming Truthful Speech, and Discernment of Karmic Consequence
एत एवंविधा देवा मनोरेव प्रजापते: । ते च पूर्व सुराक्षेति द्विविधा: पितर: स्मृता:,इस प्रकार ये देवता प्रजापति मनुकी ही संतान हैं। वे तथा पूर्वोक्त देवता-ये दो प्रकारके पितर माने गये हैं
eta evaṃvidhā devā manoreva prajāpateḥ | te ca pūrva-surākṣeti dvividhāḥ pitaraḥ smṛtāḥ ||
ビーシュマは言った。「かくして、ここに述べた類の神々は、まさしくプラジャーパティ・マヌの子孫である。そして彼らは、先に挙げた神々とともに、二つの異なる階類のピトリ（祖霊）として記憶される。」

Educational Q&A
The verse grounds the authority of ancestral categories in sacred genealogy: certain deities are traced to Prajapati Manu, and together with earlier-mentioned divine groups they constitute a twofold classification of the Pitrs, reinforcing the traditional framework behind ancestral veneration and ritual duty.
In Bhishma’s instruction during the Shanti Parva, he continues a doctrinal explanation about the Pitrs (ancestral beings), identifying their origin from Manu and summarizing that, along with previously described deities, they are recognized as two categories.
