For in the same way as physical instincts spring from man's nature, so do his positive, benign and truth-seeking impulses originate in his being, giving rise to his titanic, effulgent spiritual powers that can give birth to purity, dignity, power and righteousness. Self-Purification as Agent of Development There is no doubt that if one wants to follow definite principles in life-whether of a religious or a non-religious character-one must adopt a well-defined approach.
In order to adopt a well-defined approach it is essential to select a single goal and move in a single direction. Hence one must avoid desultory involvements that may suit one's passing desires but are contrary to one's principles and goals in life. Hence self-control and self-discipline is essential in life for every man who wants to lead a human and rational existence. Man is a being equipped with the power of intellect and possessing unlimited desires.
Should he recognize no restraint in life, he can become a bloodthirsty beast that can cause great destruction. Man's perfection and greatness does not depend on physical matters, which can affect his experience only on a sensible plane. Scientific advancements do not bring about an improvement in all the aspects of man.
Man's real perfection lies in his liberating himself from the straits of illusory lusts and physical pleasures and in advancing on the path of humanity by edifying his sensibilities, disciplining himself and becoming acquainted with higher ideas and a wider horizon. The idea of a sumum bonum (Highest Good) is deeply rooted in the human spirit, otherwise man would not have been its seeker during his childhood days nor would he have been able to take flights on its vast horizons.
The radiance of sublime values is so much attractive that men fall in love with them willingly and voluntarily pursue them. There is an upsurge of passion for strength from one's inner depths which is followed by the endeavour to acquire it. All of these are indications of the fact that love for perfection has deep roots in the human spirit and it begins to reveal itself once there arises a suitable opportunity. The muscles become strong and powerful as a result of exercise.
This is also true of the spiritual faculties, which become strong as a result of exercise and persisting effort, with the difference that the physical energies of the human body are limited and its powers are limited by the capacities of the body's sinews and cells.
