Converting to Dharmic religions, Sikhism among them, is the easiest thing. As Saurab said, it is a matter of feeling. For a Sikh, the book (Sri Guru Granth Sahib ji) is the temple and the teacher. It is not necessary to move to a place where there may be a Gurudwara (what you will term as a Sikh temple). Have you read the translation of the book? What has attracted you to Sikhism? They have a very nice system of 'Langar' (free food to all visitors, not restricted to just the Sikhs).How hard is it to convert so Sikhism? Does the person have to move to a place with a temple?
