In ancient times, the sacred rites of offering food—especially during śrāddha ceremonies—were guided by profound wisdom and careful discernment. It was taught that a Brahmin who followed the Atharva Veda and earnestly sought liberation was a purifier of the dining line, sanctifying the entire ritual with his presence. Similarly, a Brahmin who lived unattached, free from worldly desires, was also recognized as a purifier of the dining line, ensuring the offering’s purity and efficacy. But what if such rare souls could not be found? In that case, one was advised to seek out a Naiṣṭhika Brahmin—one steadfast in lifelong celibacy—a restrained person, or an Upakurvāṇa, who maintains self-control. And if even these were not available, it was permitted to invite a householder who was sincerely striving on the path. The fruit of feeding those who truly know the Vedas was said to be greater than the merit of giving a thousandfold elsewhere. If none of the ideal candidates could be found, one should then offer food to other twice-borns during the ritual, for this was the substitute procedure always upheld by the virtuous. Furthermore, it was proper to invite the daughter’s son, the lord of speech, relatives, the officiating priest, and the sacrificer himself. Yet, one must be cautious: the southern offering, if not performed with discernment, was considered demonic and bore no fruit in the next world. If the oblations were consumed by an enemy, they became fruitless after death, for offerings are not to be poured into ashes. Should an oblation be given to one who does not recite the Ṛc hymns, the giver would not obtain the intended fruit. After death, such a person would be compelled to consume as many blazing, coarse lumps as the number of such misguided acts. Wherever unworthy individuals partook of the offering, it was deemed demonic, and such a wicked Brahmin was never fit for śrāddha or similar rites. The scriptures further warned that those who lived by slaughter or bondage, and six others of such conduct, were merely Brahmin-bandhus—Brahmins in name only. Those who sold the Veda were condemned in śrāddha and similar rites, and those who officiated for the unqualified, or taught the Vedas to those unfit, were declared fallen. Kāpālikas, Pāśupatas, Pāṣaṇḍas, and others of that kind were also to be excluded, for śrāddha performed for them bore no fruit here or hereafter. Brahmins who falsely claimed an āśrama, or who begot children with widows, thieves, impotent men, or atheists, were considered defilers of the line. Likewise, house-burners, those who ate from a pit, twice-borns who sold Soma, those born of remarriage, usurers, astrologers, those with physical defects or those who had scattered their seed, betrayers of friends, slanderers, those always subservient to their wives, breakers of lineage or purity, those who touched forbidden items, who crossed the sea, murderers, breakers of agreements, and those who delighted in reviling the twice-born—all these were to be excluded from śrāddha and similar rites. Even more, betrayers of friends, deceivers, and especially those who corrupted the line of guests, as well as those who abandoned contemplation of Brahman, must be diligently avoided. A Brahmin who neglected the great sacrifices, or who was dominated by darkness or passion, was also a corrupter of the line of guests. Those who practiced condemned acts were to be strictly avoided. When the time for the rite arrived, the host would assemble all the twice-born and invite them along with virtuous people. If this was not possible, then on the following day, those possessing the prescribed qualities were called. Remarkably, it was said that, meditating upon one another in their minds, the worthy ones would come together with the speed of thought. Becoming subtle as the wind, they would remain, and after partaking in the offering, would attain the highest state. Through it all, all participants were to remain disciplined, devoted to celibacy, upholding the sanctity of the sacred rite.
