This will lead us to the highest source who is the creator of all of us and also who is in us. He also says that there are no doubts that all inspirations of love in the form of goodness comes from God within and all the destructive, inhuman qualities comes from bad influences on the outside of oneself. We must constantly use our intellect to check what is good and what is bad. Eventually this strong force will direct us to a quality that belongs to God. Through constant practice of meditation prayer and selfless service activities we will lead ourselves to self-realization.
Goodness comes from purity of the heart.
Dedication comes from prayers and loving God with all of ones heart. Sai Baba says the grace of God is like an insurance policy. It will help us if we do our duty with Love and sincerity. Whatever we put we will get it back. This is how true insurance works.
