Contrary to what some people say that ideological matters do not have any effect on human life, we think that these are the matters which form our way of living and lead it according to our ideas and beliefs. Someone who does not believe in the Source of the universe, the God of the world, and in Resurrection and the Day of Judgement will not have any relation with God, nor can he open an account in the next world to derive the benefit of his deeds. He will find himself without any obligation and will do such things which a man believing in God and the next world will not do. He can neither be unrelated to God' nor indifferent to God's guidance or the guides who have come from Him to human beings.

Even the social relations of man are linked to ideological matters. Someone who believes in God and the Day of Judgement will not indulge in crimes, cheating, unjust dealings, oppression or the exploitation of others.

Because of this deep relation between ideological matters and human life, it is necessary for everyone to study them. In order to place at the disposal of our sisters and brothers, who are seekers of truth, such ideological matters, we have prepared a set of thirty lessons in which these problems have been propounded and solved in a simple and short way. It can even be used as a text book in religious classes for youngsters. We hope you will find them beneficial and effective. Any question or comment to improve them will be welcomed.
