Does each individual have a specific path or are all paths relatively similar?
All the paths are not the same, although the ultimate goal is the same. There are different roads, but each road leads to the same goal. Each individual needs the guidance of a Master, and each individual has to discover his own path. Then he must follow only one path and one Master who is the leader or guide of that path.
Each individual must necessarily have a path of his own. That doesn't mean that there will not be other seekers on the path. There will be others who will want to follow the same path, but each seeker will follow it in his own way, according to his own inspiration, aspiration, and spiritual development.
