Hindu offers few more explanations which Islam doesn't.

Theory of micro world and macro world.

Whatever we see out side is a macro world. It includes everything animate and inanimate objects. Oceans, Mountains, Stars, Planets, Trees, Animals etc. It has physical appearance.

There is a micro world which resides in the mind. This is the world of ideas or concepts related to happiness, grief, likes, dislikes.

This micro world is unreal and makes you happy or sorrowful depending fulfilling of a wish. The whole problem lies here.

Since this world is based on concepts, it keeps on changing. Thus person's moods and decisions keep changing. Everything judged for happiness content. Even love, altruism is based on its happiness content. In fact love is directly proportional to the happiness. More the happiness, more is the love. With turn of concept, love and relationships can take a drastic U turn. Hence there should be realization that whatever is received in the name of happiness is a CONCEPTUAL HAPPINESS. happiness is never there in the outside physical objects. But the concepts are so die hard that they make you feel that there is happiness in outside objects.

Real happiness is always never ending. Thus one can arrive at decision that concept of happiness should be diverted to divine objects. Diversion will work. Hindu says direct all your emotions to God. Want a father? God is your father. Not only father, he is all in one for you. He is your mother, brother, sister, friend,lover. You can develop any relationship with him through mind. It is not the relationship but the thinking of God is responsible for purification of mind.
