purpose of life

 buddhism -- middle path 

jainism -- non-violence 

hinduism -- moksha and many other as per the school of thoughts such as 

yoga -- means understanding environment and acting as per needs,

          --for adding to environment me need knowledge i.e. gyan yoga
          --also we need a calm mind i.e. raj yoga 
         --detechment i.e. bhakti yoga 

nyaya -- it brings peace so ultimately moksha

vedanta -- 

                dwait -- male and female are different means body and mind are different so meditate on mind 

                adwait -- linga represents atma i.e. nor body nor mind 

charwak -- whatever our body can feel is real and nothing else. 

in modern times I think the puropose of life is to create options. Rich have more options than poor.
