The grace of God is the thing that is needful. One should pray for the grace of God.
One suffers as a result of one's own actions. So, instead of blaming others for such sufferings, one should pray to the Lord and depending entirely on His grace, try to bear them patiently and with forbearance under all circumstances.
He who has really prayed to the Master, even once, has nothing to fear. By, praying to him constantly one gets ecstatic love (Prema Bhakti) through his grace.
