Śrīmad-Bhāgavatam · Text 11.8.12
Who is speaking and story frame
सायन्तनं श्वस्तनं वा न सङ्गृह्णीत भिक्षुक: ।
मक्षिका इव सङ्गृह्णन् सह तेन विनश्यति ॥ १२ ॥
sāyantanaṁ śvastanaṁ vā
na saṅgṛhṇīta bhikṣukaḥ
makṣikā iva saṅgṛhṇan
saha tena vinaśyati
A saintly mendicant should not even collect foodstuffs to eat later in the same day or the next day. If he disregards this injunction and like the honeybee collects more and more delicious foodstuffs, that which he has collected will indeed ruin him.
Read the purport on Vedabase.ioFrom Canto 10, chapter 14 onward, the translation and purports were completed by Śrīla Prabhupāda's disciples after his departure, and published by the Bhaktivedanta Book Trust.
