Sai Baba was neither a house-holder nor Vanaprastha. He was a celibate sannyasi, i.e., sannyasi from boyhood.
His firm conviction was that the universe was His home, He was the Lord Vasudeo – the Supporter of the universe and the Imperishable Brahman. So He had the full right to have recourse to the begging-bowl.
(2) Now from the standpoint of ‘Pancha-soon’ – five sins and their atonement. We all know that in order to prepare food- stuffs and meals, the householders have to go through five actions or processes, viz. (1) Kandani-Pounding, (2) Peshani-Grinding, (3) Udakumbhi – Washing pots, (4) Marjani – Sweeping and cleaning, (5) Chulli-Lighting hearths.
These processes involve destruction of a lot of small insects and creatures, and thus the householders incur a lot of sin. In order to atone for this sin, our Shastras prescribe six kinds of sacrifices, viz. (1) Brahma- Yajna, (2) vedadhyayan – offerings to Brahman or the study of the Vedas. (3) Pitra- Yajna-offerings to the ancestors, 4)Deva-Yajna – offerings to the Gods, (5) Bhoota- Yajna-offerings to the beings, (6) Manushya-Atithi-Yajna-offerings to men or uninvited guests. If these sacrifices, enjoined by the Shastras are duly performed, the purification of their minds is effected and this helps them to get knowledge and self-realization.
Baba, in going from house to house, reminded the inmates of their sacred duty, and fortunate were the people, who got the lesson at their homes from Baba.
