What is the most difficult thing about your spiritual path?

Keeping faith in myself and the universe has proved to be trying many a-time. When things are seemingly going wrong or when i've got a case of the kundalini blues, it's difficult to reassure myself that this is a learning experience, just like everything else, and has a purpose, is productive. Often times, in these instances, i feel i have strayed from my path and i panic. But every experience is one with a lesson and in realizing, embracing and applying these lessons, we will never be lead astray. My destiny will always unfold just as it should :)
