Why do we struggle very hard some times? How can we get past the tough times?

I am immanent in every being. People forget Me, even though I am within and without them. I am the inner core of every being, but they are not aware of this. So, they are tempted to believe the outside world to be real and true, and pursue objective pleasures, and fall into grief and pain. On the other hand, if they concentrate all attention on Me alone, believing that the Lord has willed everything and everyone, I bless them and reveal to them the truth that they are I and I am they. Thousands have been blessed thus.
