Debipriya,
Very true the path a person follows to attain God, is from where he has left in past birth. In current birth that person gets all the required help to reach first where he was in previous birth, that is attained faster due to the experience that soul has from the previous journey, which is continued till the final goal is achieved. King Janak, Sudama etc are the example we have in front of us, who have followed different paths & attained the final goal..
