By simple observation, we understand that

Nature exists.  The Universe, there different planets, the flora and fauna – the mountains, the different rivers, the different oceans,  the different animals, the different birds, insects and also us human beings are all created by nature and they that is the proof that nature l exists.

Nature has its own system, We understand this by knowing  that due to rotation of the earth we have s sunlight and darkness.  The plant grows, change of seasons, natural life and death.

Nature regulates its own system, We can observe that the nature is very particular about regulating its own system, like it maintains the revolution/rotation of the earth, it keeps the balance  of population if excessive, birth of male and female in proper ratio, and many other factors.

Nature responds to Human behavior.

Nature has its own laws. It does not follow the rule of society, religion or land. Nature responds to your Action / In Action /  intention and Reciprocate. Nature punishes wrong action / inaction and also rewards good action / intention of a human being.

 Nature is impartial, unforgiving and having no mercy and has its own judicious and impartial punishment and reward system irrespective of power, position, money status race, etc

Every human being is expected to act in accordance with natural laws to fulfil his / her needs / destiny in their life. His every action has reaction in terms of natural laws and suitable results are decided for the individual strictly in accordance with the deed done and the intention behind the action.

But we have to remember one basic fact…. that Laws of Nature does not apply to your line of duty.. e.g. If you are a soldier, killing your enemy during war is not defying the Laws of Nature that vehemently opposes the mere action.

Humans should try and imbibe and adhere to the laws of nature in his personal and professional life.
