Here the ‘call of life’ means the call for the struggle to convey the Truth to others. Initially this struggle starts by preaching by word of mouth or by means of the pen. But the belligerent attitude of those to whom the call is given takes this struggle to various other stages, even to the extent of migration or war. Man formulates his religious life in accordance with his ideas, at the individual level. He makes his life so consistent with his circumstances that it appears to be an island of safety for him. He has the feeling that if he exerts himself to reform others, this well-established abode will be destroyed; his well organised life will be disturbed and the regulation of his time and the system devised by him to govern his property—keeping his personal requirements in view—will be upset. Such fears prevent him from making efforts to call upon others to the Truth and to sacrifice his life and property for that cause. But this is utter stupidity. The fact is that the abode of peace which he considers his ‘life’ is his graveyard, and hidden in the sacrifice in which he sees his death, lies the secret of his life. Giving the call to the people and their reformation are extremely important tasks, provided that they are aimed at the Hereafter and are not for worldly purposes. It makes a dead religion a living religion. It links man with God at the highest level. It introduces man to such religious experiences as he could never have if he remained in his individual shell. If, in spite of hearing such an important call on behalf of God, people are still unmindful of it, they incur the risk of creating a psychological barrier between themselves and the Truth; they risk losing their natural capacity to hear the voice of Truth, to rush towards it and discover their Lord. Man’s life is social in nature. Nobody can go on living on his own on an isolated island. If a man is content with his personal righteousness, he always incurs the risk that, as a result of perversion in society, he himself will also be affected, for he is also a part of the same society. His struggle to reform the people would serve as a practical demonstration that he was not involved directly or indirectly with evil people. Every evil starts in a small way and then gradually becomes greatly enlarged. If it happens that when an evil is in the initial stages, it is opposed by a number of people at that time, it will be easily crushed. But once the evil has spread, it becomes so deep-rooted that it becomes impossible to eliminate it.
