The student of development finds, not only that the chick commences its existence as an egg, primarily identical, in all essential respects, with that of the Dog, but that the yelk of this egg undergoes division that the primitive groove arises, and that the contiguous parts of the germ are fashioned, by precisely similar methods into a young chick, which, at one stage of its existence, is so like the nascent Dog, that ordinary inspection would hardly distinguish the two. The history of the development of any other vertebrate animal, Lizard, Snake, Frog, or Fish, tells the same story.
In marriage, a man becomes slack and selfish, and undergoes a fatty degeneration of his moral being.Robert Louis Stevenson
It is clear that every civilization undergoes a process of historical change. We can see that a civilization comes into existence, passes through a long experience, and eventually goes out of existence.carroll quigley
A man, who is constantly engaged in action and works hard until he has achieved his goal undergoes lots of metamorphosis and positive change which helps in his self improvement.
The most significant change in a man is not the change in his bodily strength or mental capacity. The most marvelous and far-reaching change which man ever undergoes is in his moral character and spiritual nature.
If you begin to understand what you are without trying to change it, then what you are undergoes a transformation.jiddu krishnamurti
