Note 290 — Chapter CXXVII · NARADA'S ADVICE AND INDRA'S ANSWERS.
Manmatha Nath Dutt translation
The author means that true and faithful friendship and love exist only between brothers;—between other parties it is merely a mockery, a business—that of maintenance and support. The wife loves the husband for he supports her—the old parents love their son because he is their maintainer and so forth.
