What are the blessings of Tahajjud? What can we do if we miss the sweetness and joy of the night prayer? Those who have no experienced its beauty will not know what makes the righteous cry during it. 

The people who perform tahajjud experience a sweetness that his far greater than the joy of the sinners subhanAllah!

While striving and patience it will take time. When you force your soul to go towards Allah the soul has to surrender.
