A Poor, needy and physically challenged person, who is unable to do any kind of "Sewa" for anybody, or in Gurudwara sahib. But is perfect in doing "Simran" everyday. As it is being discuss in another thread that "Sewa" is more important for one "Sikh", But such kind of peoples are ever helpless to do so, but they can do "Simran" easily. Is such person eligible to call himself/herself as "Sikh" ? Can such person never attain enlightenment ? Which kind of "Sewa" can such person do ?
