I agree all those things body, places we live in, society, personalities, even people who we consider to be our parents can be changed again and again. I have actually done this several times in this life alone just to prove to myself I am not fixed to just one body, place, society, personality. I done such radical things that most people would dare not to. However, there is obviously a baseline that I have always adhered to, but I think if went to the extreme, I could probably change that baseline as well.
The thing is we should not arbitarily change things. There must be a reason to change and a lot of insight for that can come from remembering your past life or remembering what goals were actually set right before you incarnated. For example suppose for the last 5 past lives you were working on overcoming a particular fear, say fear of speaking to others, if you knew that this was your goal in this life it would become so clear and you can get right onto working on it.
Then again I guess even if we introspect a bit we can come to know what exactly we need to work on in this life. In general I think our challenges in life come under the following categories: social, physical, emotional, mental, intellectual and spiritual and we need to identify the challenges we are facing in each sphere and work on all of them holistically. I guess following a complete Yogic lifestyle is the best antidote to that.
I have recognised my problem in each sphere as follows:
- Lack of empathy with others, love and inability to open to others(I can open to some people)
- Lack of energy and drive, tension in jaw, shoulders, need for more flexibility
- Very left-brain, scientific, rational, lacking creativity, poetry, colour
- Too much thinking, too little doing
- Poor short term memory and poor mathematical and motor skills(need to do sport!)
- Aversion to bhakti/devotion, need guidance
The solutions to the above challenges are inherent in the challenge itself. Such as taking up a creative activity to engage the right-brain, and doing a physical sport and physical exercise to boost energy levels.
