Absolute faith (Shraddha) and patience (Saburi) with courage, these are the Uma-Maheshwar and unless their hand of benediction falls on the head, that all pervading almighty who dwells in our hearts can never be realized – Have a little patience and perseverance of a firm faith and you will acquire the greatest glory – Sai Baba of Shirdi

Live in the midst of the battle of life. Anyone can keep calm in a cave or when asleep. Stand in the whirl and madness of action and reach the center. If you have found the center, you cannot be moved – Swami Vivekananda

Serenity of the mind, gentleness, silence, self-control, and purity of heart – these are said to be mental austerity – Sri Krishna in the Bhagavad Gita (Ch:17;14-16)
