I am Shia.The moment I started reading self help and motivational books I felt myself going away from God. And my belief below is valid. Please solve my doubts.
1. Science says you can achieve everything just by training your brain. then why should I pray Salah and cry before God and ask everything
2. people who do yoga and train their minds are also succesful

Praying and making Dua does not mean that you don’t train your brain. Train it by all means but you have to know that the creator of the brain is also the one in whose hands all the outcomes are. It is my responsibility to work, it is his responsibility to give the outcome. Similarly, nothing wrong with yoga and other things. Shariat is the way to train ones self spiritually just as these self help are good for psychology
