We do sadhana regularly yet we face difficulties. Why is it so?

Question - Gurudev, we do sadhana regularly yet we face difficulties. Why is it so? 

Gurudev Sri Sri - It is only when you face difficulties that you ask 'Why do I face difficulties?', you never ask 'Why am I happy?' when you are happy. When we face difficulties, sadhana gives us the strength to face it, to overcome it. Things have changed and will change. Have faith.
