Alright then. Traning in clairvoyance can help you see him and training in clairaudience can help you hear him. If you have a guide that's great because they can help you in training. An effective guide can shorten years of works to few months IF done correctly. Mainly meditation on your astral ears and eyes will do the trick. Ask him for help in meditation, he probably knows how energy should be guided in those areas already. 

For regression, they do work but there's few problems that might occur. If the person already has a delusion about their past life(most have), they usually see the deluded visions and not the real deal. Also if the therapist has bad intentions, information about someone's can be huge blackmail material if done correctly. Most people doesn't change a lot between lifes if you had suicidal tendencies or drug addiction in your past, you probably do now. Or other secrets you might hold. If you can so it by yourself, great! If not, find a trustworthy therapist if you wish to do so.
