The Indian mythology has a theory of cycles, that all progression is in the form of waves.
Swami VivekanandaThe first angle is, love questions not. It is not a beggar. ... When love asks nothing, [when it] gives everything. This is the real spiritual worship, the worship through love. Whether God is merciful is no longer questioned. He is God; He is my love. Whether God is omnipotent and almighty, limited or unlimited , is no longer questioned.
Swami VivekanandaIf religion and life depend upon books or upon the existence of any prophet whatsoever, then perish all religion and books! Religion is in us. No books or teachers can do more than help us to find it, and even without them we can get all truth within. You have gratitude for books and teachers without bondage to them; and worship your Guru as God, but do not obey him blindly; love him all you will, but think for yourself. No blind belief can save you, work out your own salvation. Have only one idea of God - that He is an eternal help.
Swami VivekanandaFill the brain with high thoughts, highest ideals, place them day and night before you, and out of that will come great work.
Swami Vivekananda
