“The appearance in the mind of undesirable and ignoble thoughts, even if they are very fleeting and only half-articulate, has an unpleasant effect upon one’s self-esteem. Therefore such thoughts are often shoved aside, unattended to and unopposed. Often they are also camouflaged by more pleasing and respectable labels which hide their true nature. Thoughts disposed of in either of these two ways will strengthen the accumulated power of ignoble tendencies in the subconscious.”

Indian Spirituality and Life (1919)
Context: The Infinite alone justifies the existence of the finite and the finite by itself has no entirely separate value or independent existence. Life, if it is not an illusion, is a divine Play, a manifestation of the glory of the Infinite. Or it is a means by which the soul growing in Nature through countless forms and many lives can approach, touch, feel and unite itself through love and knowledge and faith and adoration and a Godward will in works with this transcendent Being and this infinite Existence.
This Self or this self-existent Being is the one supreme reality, and all things else are either only appearances or only true by dependence upon it. It follows that self-realisation and God-realisation are the great business of the living and thinking human being. All life and thought are in the end a means of progress towards self-realisation and God-realisation.
