Gurudwara Bangla Sahib is a revered Sikh shrine in Delhi.
Guru Har Krishan, the eighth Sikh Guru, stayed here in the 17th century.
During a smallpox and cholera epidemic, he provided water and aid to the suffering.
Eventually he succumbed to the illness himself.
Today, the gurdwara stands as a symbol of selfless service and compassion.
