Amidst the din and boisterous bustle of worldly activities there come moments of tranquility and peace, when the mind for the time being, however short it may be, soars above the filthy worldly things and reflects on the higher problems of life, viz. "Whence? Where? Whither? Why of the universe? Who am I?"  The sincere inquirer becomes serious and extends his reflections.  He begins to search and understand the Truth.  Discrimination dawns on him.  He seeks vairagya, concentration, medittion and purification of the mind and body, and eventually attins the highest knowledge of the Self.
