The Sikhs have fought and won numerous battles in past, often against heavy odds. This has been possible, I believe, not only on account of immense courage, but also a strong sense of self-discipline. Sadly, many of those who call themselves Sikhs, nowadays, seem to have given up the latter, along with their Kesh (unshorn hair and, in the case of men, beard as well).
The following photgraphs were taken at Keshgarh Sahib, a few days ago. The painted signs are meant to request members of the Sangat (congregation) to deposit their shoes at the designated place, from where they could collect these before leaving the premises, simply by returning a token issued against the shoes. The service is provided free of charge.
