धर्मस्य बहुद्वारत्वम् — Nārada’s Audience with Indra (Śānti-parva 340)
नावासुदेवभक्ताय त्वया देयं कथंचन । नरेश्वर! इस प्रकार यह ऋषिसम्बन्धी आख्यान परम्परासे प्राप्त हुआ है। जो भगवान् वासुदेवका भक्त न हो, उसे किसी तरह भी इसका उपदेश तुम्हें नहीं देना चाहिये || १२५३ || (आख्यानमुतन्तमं चेदं श्रावयेद् यः सदा नृप । तदैव मनुजो भक्त: शुचिर्भूत्वा समाहित: ।। प्राप्रुयादचिराद् राजन् विप्णुलोक॑ सनातनम् ।) नरेश्वर! जो मनुष्य सदा इस उत्तम उपाख्यानको सुनायेगा, वह भक्त मनुष्य पवित्र एवं एकाग्रचित्त होकर शीघ्र ही भगवान् विष्णुके सनातनलोकको प्राप्त होगा ।। मत्तोडन्यानि च ते राजन्नुपाख्यानशतानि वै

Bhishma said: O king, you must never impart this teaching to one who is not devoted to Vāsudeva. Thus has this account, connected with the sages, come down through an unbroken tradition. Whoever is not a devotee of the Blessed Lord Vāsudeva should not, in any manner, be instructed in it by you. And, O ruler, the man who regularly recites or causes this excellent sacred narrative to be heard becomes a devotee—purified and collected in mind—and soon attains the eternal realm of Vishnu. Moreover, O king, I have hundreds of other instructive tales to tell you.
भीष्म उवाच
Sacred instruction is to be entrusted only to those who have devotion to Vāsudeva; faithful hearing/recitation of such a narrative purifies the mind and leads to the eternal realm of Vishnu.
Bhishma, addressing the king, concludes an inherited rishi-tradition account by warning against teaching it to non-devotees, praises the spiritual fruit of regularly reciting it, and then signals that he has many more instructive tales to relate.
