PURPORT

Bidhi means Brahma the first created living being. He is the original student as well as professor of the Vedas as He learnt it from Sri Krishna and taught Narada first. So Narada is the second Acharya in the line of spiritual disciplic succession. He is representative of Brahma and therefore He is respected exactly like Brahma the father of all Bidhis (regulations); similarly all other successive disciples in the chain are also equally respected as representative of the original spiritual master.
