We talked about purification of soul and we said that if human being receives the real knowledge, the light of knowledge, he will be purified by the same light. So, purification of soul is related to knowledge of truth and light. Just as obtaining light of knowledge is related with purification of soul which is a bilateral relation.

When one takes much care and controls every second, i.e. when he makes it a condition with God not to make errors in this day and mediates throughout the day, and considers all his actions whether it is good or evil and if he makes evil, he penances, such a being will result in purification of soul and we shall purify our souls.

It has been narrated that “There is a light in knowledge which Almighty God will throw it to every heart He wishes.” This narration is related to the verse, where God prescribes: “If you call me, your wish shall be fulfilled.” When we seek knowledge and truth, God will select us. If we request God in all our worship to grant to us light of knowledge and we pray for it, God will grant us the same light. Our minds and out thoughts shall be lighted. Each heart seeking for alight knowledge, God will seek the same to him, but the time will be determined by God. we might afford obtaining knowledge, but it is God Himself Who shall determine when He Will Bestow to us the light. We should not exit our borders. God will bestow to us the light whenever He Wishes. He will determine the time when we ask him and He observes our ability. But when will He fulfill our wish in practice? It is whenever He Wishes. Hazrat Ali (p.b.u.h.) prescribes: Those who seek knowledge, will attack to foresight and those who do not like the outward knowledge, will not seek it.”

One who seeks the real knowledge, will seek the light of all sorts of knowledge and will avoid the knowledge without light. He only seeks the inside and essence of sciences and considers a knowledge for which he will make attempt and will reach the same light. He will tolerate all the troubles and takes easy all the difficulties and see all of them as graces.

To reach the essence of each knowledge, each worship, each creature, we shall pass the outward border. It means that we should completely perform the appearance to reach the essence and to comprehend the light. For example, the appearance of a worship like praying is the same as avoiding polluted dress and making the recommended and the obligatory acts and making the preliminaries of praying such as minor ablution, call for prayer. To comprehend the essence of praying, we should perform ablation, praying, obligatory and recommended acts and to think about essence of praying at the same time, to purify ourselves. Consequently, to reach the soul of praying, we should accompany the appearance of praying with thought. So, comprehension of essence of every thing shall depend only on our purification. We should break the wall we have constructed around us to comprehend beyond it. We know about the appearance of knowledge and praying and observe it, but we do not know the essence.

It has been narrated: “Praying is an ascent of the faithful people” but have you ever thought that why we do not reach the ascent by praying? Because of lack of pureness and purity of inside us. We should make some changes in our thoughts. We should pay more attention to our inside. Then we will reach comprehension of our inner soul. Our goals should be sacred. If we study medicine, we should seek light of medicine. Light of science needs transparent pages. The transparent page is our inward.

Prophet of God prescribes: ”The angels do not enter a home where a dog lives. Here, he means an animal, named dog who will transfer many diseases. If we pay a little attention, we will find out that some people behave like dogs so the angels will not enter the house where such a man lives. Even if we behave like a dog for one hour, the angels will not enter out houses. It means the meaning of the narration. Because the surface meaning of the narration talks about an animal named dog, but the deep meaning is a human who acts like a dog. This way, an important stage is purification of inside and the next stage is thinking and reasoning about the science and its attainment. This is about reaching attainment.

It has been narrated from prophet of God that he stated among his friends: “You should not act this year just as the last year”. Then he paused and said: you should not act this month just the same as your last month. Then again he paused and said: you should not act this week just the same as your last week. Then he again paused and said: You should not act today just the same as yesterday. He added: your present minute should not be the same as your past minute. In the end he said: your present second should not be like your pas second.

In fact according to this narration, the human beings are classified. Some are the people who will understand their failure the next year. Some understand it after one month and some after one minute and some at the same minute they are committing the crime. So, if prophet said your present second should not be the same as your past second, it means that evolutionary movement of those who seek attainment means to avoid all the evil one had the previous year, so having such a model we understand how to attain this goal. We should learn from the book: Merajol Saadat how to walk, how to run, how to fall down and how to stand up, but we should know that the real leader is God. We should go to reach the utmost all the far distances. Of course taking this path we are hopeful to 14 innocents (peace be upon them) who might take our hands and might assist us. It is worth mentioning that our being a human necessitates that we do not make blunders. But it is important to understand that God has created us pure and we should reach the degree of successors of God on the earth. Of course just as God likes us to be his successor on the earth, He will  help us Himself. He let us study and paves the way for us. It will be enough if we meditate, do not depend on the world, love the hereafter. We are living in this world but we should live for the hereafter. If we exit ourselves, we will be like Horr Ibn Yazid Riahi who left his previous life though he was an aged man. So, the age, literacy, money, .. shall not make our criteria. If we are not separated from this world, we will not be able to gain the truth. Even if we are bothered, we should stand and should make efforts for the hereafter. Since, the world and the hereafter are not joined. In paradise, the poor have a rank, the reach can not have. It is the same in the world and considering spiritual ranks. The spiritual ranks and the world can never join. One who enjoys welfare in the world, will not be sorrowful for the life and for money, to the same proportion, in the future world, he will lose a part of paradise. He prescribed according to the same narration: “The world is the farm of the Hereafter”. The more we are bothered in this world, we will reclaim our future. One who governs on his family or the people, will have no reign in the hereafter, even if we are so good that we are not tortured there, and even if we hold spiritual ranks, we will lose in the hereafter the same welfare. For the same reason, the innocent (p.b.u.h.)  having so much wealth, were living like the poor. In the houses of our Imams food was not quickly made. The kitchens of their houses were lighted the last in the city. It was the rule of all Imams. Imam Mousa Kazem (p.b.u.h.) was imprisoned for thirteen years. He was a powerful man, but he was satisfied with God’s wish. When the people were taking oath of allegiance with Imam Ali (p.b.u.h.), a Jew entered and asked: Who is he? They said, He is Ali (p.b.u.h.). He asked: Is he the same person who captured Khaibar? Why don’t he kill them? They replied: because God has ordered him to keep silent not to rebel. The Jew said: If he is keeping silent for the sake of Islam, so I convert to Islam. And then he converted to Islam. 100 Jews converted to Islam, witnessing silence of Ali (p.b.u.h.). He made 100 people converted to Islam by his silence, so we should see what he did during 25 years of his silence. He attracted the hearts to himself by his silence.

If praying keeps vice and prohibited acts far from man, and God prescribes in Sura: Ankabout, verse: 45: “Indeed, praying will keep you away from vice and prohibited acts” so why so many people pray but they seek prohibited acts? When some one is seen naked by others, how can he conceal his body at praying.

Imam Khomeini stated before his death: “It will be sufficient to me if I have prayed two units which have been accepted by God.” this is praying which removes lust and prohibited acts and will let man ascend.

If we do not obtain the true knowledge, if we are not aware of essence of the affairs, we will shout in the future world, as Mulla Ahmad Naraghi said: “Alas! Because I faulted in obeying God (Sura: Zamar, Verse: 56).

Those who shout like this, will go to Paradise. They will say: “Alas! I hope I had not done it! I hope I had not told this. They are with God, next to him. and shout: This book will teach to us that in a farm capable to grow the plants, how they should lay seeds so that the plant is green and grows healthily to be attained and this is the objective of this book.
