“sanksipya caturo vedams caturdha vyabhajat prabhuh vyasta-vedataya khyato veda-vyasa iti smrtah”
“The prabhu (master, lord, guru) who is most intelligent then divided the Vedas into four. He therefore became known as Veda Vyasa.”
He codified the Veda, the compilation of which was initiated by Maharshi Angiras two millennia back, into four divisions ( 1131 Sakhas or Recensions divided into Rik (21 sakhas), Yajur(101=85+16 sakhas), Sama (1000 sakhas) and Atharva Veda (9 sakhas). For further re-organization and editing he entrusted the Books to his trusted disciples:
Rig Veda - Paila
Yajur Veda - Vaisampayana
Sama Veda - Jaimini
Atharva Veda - Sumantu
21(Rig)+101(yajur)+1000(Sama)+9(Atharv)=1131 Vedic branches had 1131 Samhitas, 1131 Brahmanas, 1131 Arynaks and 1131 Upanishads. These 1131x4 = 4524 scriptures together came to be known as Vedic wisdom.
