Premanand Maharaj Ji
How does karma work in my life?
As you do, so you taste
"Karma pradhan vishwa rach rakha, jo jas kare so tas phal chakha": the world is made with karma at its centre, and each person tastes the fruit of what they do. The unequal lot of people comes from their karma, not from any fault in Bhagwan.
The world was made with karma at the centre, and whoever does whatever, tastes its fruit. Where is God's fault in this? Whoever does a given karma gets that fruit.
