A great proof of religion being a naturally intrinsic part of humans is the research done by the psychologists on human psyche from various angles.

(1) Sense of Wisdom, (2) Sense of Adornment (3) Sense of Goodness and (4) Sense of Religion are proofs themselves. Some specialists have enumerated five senses (1)

The continued search for truth (2) the search for good behavior (3) the search for adornment (4) Search for extreme beauty and discovery 5) the search for love and worship. Evidently the search for truth and the search for beauty and discovery are not separate from each other. (2)

This is a yearning which urges man to discover the secrets of knowledge and this world and those that are linked or not linked with his life. This yearning includes them all e.g. the urge to know the condition of this world a year before or what will be its condition a million years later or those worlds that exist some hundred thousands of light years away. We have the urge despite this information having no directed bearing on our lives or otherwise. It is this urge that leads the birth of various kinds of information and knowledge.

Every person feels this in the depth of his soul and this is what urges him to create and innovate and leads to different forms of art.

Polite behavior, adherence to rules, justice, freedom and truth are created because of it. It is possible that a large number of people do not practice or adhere to it but there is no doubt that in the core of their hearts they like these things.

This is the fourth after the human soul that urges men to perfection and it is named after God. This is what enjoins people to religion without needing any proof. It believes in God and it is possible that it is not free of frivolous contamination in religion and includes idolatry and shamanism (worshipping the sun and the moon) but it can be asserted that the need for God exists.
