Hey Guys ! How can you think eyes are the simplest part. You see, your eyes never lie when you want them to, they cannot hide your thumping heart when you see you crush, nor can they conceal the smile when you want them to.

Imporatance Of Human Body
HUMAN BODY IS LIVING IDOL OF GOD
Satguru considers the human body to be the walking and talking living idol of God made by God Himself. He has taught the ideal worship of the living idol of God which consists of
by nurturing the human body with good Sanskaras or impressions and excellent habits;
by culturing the human body well with an excellent education, training and teachings;
by nourishing the human body with good food, pure milk and water, etc.;
by maintaining the human body in sound condition with peaceful mind by entertaining good thoughts in the mind, speaking pleasant words, performing good actions, remembering God with gratitude, performing physical exercises or Yoga; and
by constantly striving for both material development and spiritual progress. He emphasizes that by worshipping God in the way mentioned above, human beings can positively attain happiness, peace, contentedness, bliss, health, success and prosperity.
Conversely, those who become addicts of undesirable vices like alcohol, smoking, chewing tobacco, opium, heroin, brown sugar, etc., actually vandalize and insult the living idol of God in the form of the human body. In the same way, by indulging in abuse, corruption, atrocities, harassment of people, violence, murders, etc., human beings actually torture, damage and demolish the living idol of God in the form of the human body. Satguru maintains that people who indulge in such bad and evil actions are terrible criminals in the eyes of God and they are meted out their punishment as per the Universal Laws of Nature in the form of physical diseases, mental diseases, troubles, catastrophes, calamities, tensions, unhappiness, misery etc.
