Karma

Family Family scripts (religion, diet, class, school, peers, language, parents job--as seen acted out in soaps, compare Eastenders to Upstairs Downstairs). 
Body type Body scripts (parent body types--the 4 body types, helped by parent eating scripts.  Also the blood types seem to dictate diet, eg O type are more meat eaters)
Genetic disease traits Inherited disease traits (miasms).  Possible to deal with miasms through homeopathy. Also Vedic astrology uses gem rings to ward off disease, as described in Autobiography of a Yogi by Yogananda.
Culture Country scripts (you can see these by comparing Iran with UK, and then North UK to South UK)
Past Life bad deeds Seems to come out as disease--Sondra Ray mentions the man who deflected this karma by helping disabled kids.
Past life conflicts with other people Conflict in this life with other people that has no logical source in this life. Dealt with by soul retrieval?
Present life bad stuff scripted in As seen in Vedic astrology, where they claim to be able to predict the date of death, for example. This is the one that needs thinking about--can you stop or influence negative stuff such as deaths, injury? Vedic astrology using gems?
Instant karma Negative deeds in this life.  Eg salting sheep water to increase killing weight came out as shingles in one farmer according to a homeopath
Past life activities Do past life activities influence this life, eg do some souls choose to explore one area of aspect in life?  It looks that way as some people seem to concentrate on different aspects eg shamanism, healing.  Also that past life knowledge seems to be available on some level, as some people gain knowledge and skill very quickly in their chosen areas.
Future life Zoosh says you can call your future lives knowledge in to your present life to help you.
   

Questions:

How many lives do souls have running at one point in time.  According to Robert Monroe his soul has another life alive at this point in time. 

Presumably there are old souls and newer souls--how are souls created, who or what decides to create souls and do they split off from other souls or are they created?
