More shlokas from texts on purvasevā on haviṣyānna shall be posted as and when convenient. A further thing to note is the insight of Adi Shankara where he notes that AhAra is not just what we intake by our mouth but by all our sensory apertures as well like our sight,the music we listen to,and in modern times, would extend to the media we consume.
The shlokas below are posted from the Puraścaraṇollāsa tantra compiled by Swami Paramatmananda Bhairav with a few of my remarks intersperesed here and there
I am not going to deal with the question of acceptance of bhīkṣā because if the audience this is meant for has computers and electronics,they are unlikely to be the ones in austere conditions needed to accept bhīkṣa.
On the importance of bhakṣyābhakṣya niyamas at all stages of tantric practice,Gautamīya states
puraścaraṇakṛnmantrī bhakṣyābhakṣyaṃ vicārayet।
paśavānāñca vīrānām divyānāñca maheśvarī॥
śastānnañca samaśnāyanmantrasiddhasamīhayā।
tasmāt sarvaprayatnena śastānnāśi bhavennaraḥ॥
Kulārṇava
yasyānnapānapuṣṭāṅgaḥ kurute dharmasañcayaṃ
annadātuḥ phalasyārdhaṃ kartruścārdhaṃ na saṃśayaḥ
(bhīkṣāyāṃ tu vihitatvāt na doṣaḥ)
(If one takes from from another’s house,they get half the merits,there is no doubt about it).
