Why I cant vote from Mumbai for Lucknow candidate, when Sanju can contest?

Being citizen of country we have right to contend as candidate from any of the constituency in India, but why we can not vote at any of the constituency we like? I think somewhere we go wrong either for candidature or for voter. It seems ridicules that the person stays in one constituency stands as candidate for other constituency. It is wrong practice & EC should modify that a candidate supposed to be the residence of the constituency or voter supposed to have right to vote at other constituency, simultaneously candidate supposed to fill the form why he wants to contest the election? What is primary motto?. The EC should not allowed any candidate who gives stale or baseless promise, which is absolutely not possible even by majority. The major qualification for candidature is that a candidate supposed to executed his or her voting rights at least for last election.
