Observation in itself is a concentration when it is keen and well-focused. The keenness of observation comes from the clearness of mind and from the appreciation of beauty. Clearness of mind: The mind becomes clear when it is stilled, as the reflection is clear in water which is still. When the water is disturbed, the reflection becomes blurred. Appreciation of beauty: For appreciation of beauty, love for beauty is necessary, which is inborn in the artist, but is developed by a continual tendency to admire all that is beautiful.
