It is also narrated with reliable chains from Abu Hamza Thumali that Imam Baqir (a.s.) told him: Whenever anyone of you goes on a journey of even a few miles he is accompanied by a guide so that he may not go astray. You are less aware of the heavenly paths in comparison with the earthly roadways. So search for a guide from you for your guidance. What is meant by the heavenly paths is that they are some beliefs and deeds whereby man attains higher ranks near Allah and in heavens (Paradise).
