sabe vasi' krame krame bhojana karila
brāhmaṇa-brāhmaṇī-gaṇe āge khāoyāila
sabe—all; vasi'-sitting; krame krame—by and by; bhojana karila—honored prasāda and ate it; brāhmaṇa-brāhmaṇī-gaṇe—the brāhmaṇas and their wives; āge—first; khāoyāila—were fed.
All the people gathered there sat down to honor the prasāda, and by and by they took food. All the brāhmaṇas and their wives were fed first.
According to the varṇāśrama system, the brāhmaṇas are always honored first. Thus at the festival, the brāhmaṇas and their wives were first offered the remnants of food, and then the others (kṣatriyas, vaiśyas and śūdras). This has always been the system, and it is still prevalent in India, even though the caste brāhmaṇas are not qualified. The system is still current due to the varṇāśrama institutional rules and regulations.
