BAOLI or bavali is a masonry well with steps leading down to water level. This is perhaps the oldest type of well introduced when man had discovered the existence of subsoil water and also the means to reach it, but had not yet invented mechanical devices to draw water out of it. Before masonry art was developed, baolis must have been only shallow pits with a sloping path down to the water, vertical walls and dented steps confined only to rocky regions.
PANGAT, from Sanskrit pankti (lit. a row, line, series, or a group, assembly, company), stands in Sikh terminology for commensality or sitting together on the ground in a row to partake of food from a common kitchen regardless of caste, creed, sex, age or social status. Pangat is thus a synonym for Guru ka Langar, an institution of fundamental importance in Sikhism. It is customary for diners in the Guru ka Langar to sit side by side in a pangat or row when food is served to them by sevdddrs or volunteers. The institution of Guru ka Langar itself thereby came to be referred to as pangat.
