If you see, very young kids, they don’t have fear when the mother is taking care of them. But when a kid starts walking on its own, then he looks around here and there very carefully. So, fear comes around that time, and it disappears when the mind or the intellect get mature. A mature intellect has no fear.
Just like you run out of fuel in the car and you have to refill it again and again, in the same way your dedication and commitment runs out in the course of time and it needs constant renewal!
You have to dedicate and rededicate again and again.
Often people take their dedication for granted and then the mind starts demanding or complaining. When dedication is not complete, it leads to grumbling and complaints.
Total dedication brings enormous enthusiasm, zeal, trust, and challenge, and does not leave any room for ego.
