SB. 12.13.13:
prausthapadyam paurnamasyam
hema-simha-samanvitam
dadati yo bhagavatam
sa yati paramam gatim
"If on the full moon day of the month of Bhadra one places Srimad Bhagavatam on a golden throne and gives it as a gift, he will attain the supreme transcendental destination".
Purport:
One should place Srimad-Bhagavatam on a golden throne
because it is the king of all literature. On the full-moon day of the month
of Bhadra, the sun, which is compared to this king of literatures, is present
in the constellation Leo and looks as if raised up on a royal throne. (According
to astrology, the sun is said to be exalted in the sign of Leo.) Thus one
may unreservedly worship Srimad-Bhagavatam, the supreme divine scripture.
