When you brief on the Holy Books, you will find that triple link among prayer, thankfulness and joy; there is no separation among the three of them.
Starting with anyone of them will let you reach the two others.
If you started with the prayer, you'll be led to thankfulness and you'll gain joy.
If you started with thankfulness, you would express it through prayer when you'll be filled with joy.
If you started with joy and lived in the real happiness, you'll find yourself praying and thanking automatically.
Those three are attached altogether
