If you want peace of mind, do not find fault with others. Rather see your own faults. Learn to make the whole world your own. No one is a stranger, my child; the whole world is your own.
When one realizes God, He grants knowledge and illumination from within; one knows it oneself. In the fullness of one's spiritual realization one will find that He who resides in one's heart, resides in the hearts of others as well - the oppressed, the persecuted, the untouchable, and the outcast.
Continue to pray without losing heart. Everything will happen in time.
If anyone surrenders himself totally at his feet, the Master will see that everything is set right.
One's love of God depends entirely upon one's inner feelings. Love of God is the essential thing.
