I was living an extremely burdensome life, because every time I prayed, I became more clearly aware of my faults. On the one hand, God was calling me. On the other, I was following the way of the world. Doing what God wanted made me happy; but I felt bound by the things of this world.

This quote is about feeling conflicted between what God wants and what the world wants. The person who said it was feeling weighed down by their spiritual life, because praying made them acutely aware of their own shortcomings. Despite this, they still felt pulled towards what God wanted for them, knowing that it would bring them joy, but feeling held back by the demands of the world.
