Guru said this world is a drama enacted by God using five tools; namely
The creature possessed by these 5 (together known as 'haumen' the ego) is madly active in the life process unmindful of the fact these these five will ultimately become responsible for his end.
Guru sahib has said once you understand this phenomenon i.e the Will of God or Hukam or the administration of universe, you will no longer be stung by the poison of Ego.
SEX- God created the sexual urge and thus indulges and the outcome is baby for which he was least mindful.
ATTACHMENT -Then the man claims, "It is my son" my baby. This attachment forces him to nourish the baby.
ANGER - Any threat to his baby or his property and the man gets angry and will fight to the finish.
GREED - To make his baby or his property grow, he will endeavour to bring more and more money or property for the future comfort of his baby or property.
PRIDE - He becomes proud of what he has achieved. People do praise him on his face and he is elated to hear that.
This way the man remains active throughout his life never bothering that one day he will have to abandon this all.
But Guru does not advise us to leave this all and become a hermit. He advises us to participate in this life process but understanding its true meaning so that you don't feel cheated in the end. One should not be too much involved in it to do bad things. One should enjoy being an actor in this great drama and taste Anand the ecstasy. When you are reasonable attached, you will not do wrong things to achieve more. When you are reasonable attached you will not take loans to make a pomp and show at the marriage of you son/daughter. Naturally you will not have to commit suicide because of loan. You will not indulge too much in the ceremonies or pomp or show. You will enjoy your reality. Life will not be hell for you. You will not be completely broken when you are abandoned by son or daughter. Because you know the limits of attachment.
So how can we be happy (truthful) and how the curtain of falsehood between us and the great drama (God) will be removed?
ਕਿਵ ਸਚਿਆਰਾ ਹੋਈਐ ਕਿਵ ਕੂੜੈ ਤੁਟੈ ਪਾਲਿ ॥
The answer is submitting to the will of God
ਹੁਕਮਿ ਰਜਾਈ ਚਲਣਾ ਨਾਨਕ ਲਿਖਿਆ ਨਾਲਿ ॥
And when you tend to know you limits and know that real power lies in the hands of Creator, you automatically begin praising the Lord
So when the whole world is sleeping you get up and think about the greatness of the Creator and praise Him. Then you realise that is was due to your past activity that you are under the present circumstance. You realise that when He is pleased you will be liberated from these. Then we know that it is God Himself every where. The entire creation is He himself.
