The spirit soul is ever fresh. He is always different from the material body & mind is always subject to disturbances.
If God wants to kill somebody, nobody can protect him and if God wants to protect him, nobody can kill him.
As a leader my duty is to make Krishna Consciousness so exciting for you that you even stopeating and sleeping! It automatically happens when you are excited. Krishna Consciousness must be like that.
Taking to Krishna consciousness and bringing fallen souls to Krishna consciousness is victory for Lord Krishna.
Srimad Bhagavatam 6.16.40
