Samadhis may not contain mortal remains but still they are solemn relics which mainly perpetuate the last rites of a distinguished entity. Mahatma Gandhi, Jawaharlal Nehru, Indira Gandhi, Rajiv Gandhi, Jagjivan Ram and Chaudhari Charan Singh -- all have such memorials which are greatly revered. However, there are much older samadhis whose history is lost over the centuries. An example of that is the Rajput ones, particularly of Jaipur.
