Karma generated by pride locks a person in the wheel of samsara. Pride is the unity of fear, lies, and ignorance, which give rise to illusions and dukha. In fact, lying is an illusion, dukha is suffering, and ignorance is their own mother.
The hardships and sufferings of your life consist of all that you consider bad and unjust. There is too much darkness around you, and you live in darkness and tremble with fear. If you become enlightened, the darkness will turn into light and the fear will recede, taking all your worries with it.
To let go is to trust and stop fighting reality. As long as you don't struggle with the burden, it doesn't exist. You fight because you have no faith. Faith is love. Pride is the absence of love. Love is joy and energy. Against the background of the absence of love, there is an acute thirst and hunger for pleasure, the absence of which generates fear.
