love from viewpoint of Christianity and Hindu and its evaluation

Some ~Christians~, who present themselves and their religion as messengers of peace, believe that the ~perfect man~ possesses nothing but love, thus he has nothing but the power of attraction, and perhaps some Hindus also believe the same thing.

One of the things that is very striking in ~Hindu philosophy~ and Christian philosophy is love. They say that one must cultivate affection for all things and make one's love manifest, and when we come to love everyone what can possible prevent everyone from loving us - the bad will also love us, since they will have seen our love.

The necessity of connection between love and reality
But these gentlemen should understand that it is not enough merely to be a man of love, one must also be a man with a path, just as ~Gandhi~ said: "~This is my religion~." Love must coincide with reality and, if it coincides with reality it will have some path which it follows, and following a way creates enemies, whether we wish it or not. In fact, it is the power of repulsion which incites one group to struggle and excludes another group.

Islam is also the law of love. The ~Qur'an~ presents the ~Holy Prophet~ as a mercy for all Being: (rahmatan li'l alamin)
We have not sent thee, save as a mercy unto all beings (Anbiya', 21:107).

This means that you (i.e., the Prophet) should be a mercy even for the most dangerous enemy, and should love even them.

However the love which the Qur'an commands does not mean that we should act towards everyone in conformity with what he likes and what is pleasing to him, that we should behave towards him in such a way that makes him happy and necessarily attracted towards us. Love does not mean that we leave everyone free to follow their inclinations, or still more that we should approve of their inclinations; this is not love, rather it is hypocrisy and double-dealing. Love is that which coincides with reality, it causes one to reach good, and sometimes those things which bring us to the good take a form that does not attract the love and affection of the other person. How many individuals there are to whom someone is loving in this way and who, when they observe that this love is at odds with their own inclinations, become hostile instead of appreciative. Besides, rational and intelligent love is that in which is the good and interest of the whole of mankind, not the good of one individual or one special group. There are many things which can be done to bring good to individuals and to show love for them which are the very same things which bring evil to society as a whole and may be its enemy.

We can find many great reformers in history who endeavoured to ameliorate the situation of society and smooth its sufferings, but who, in exchange, received no acknowledgement but animosity and persecution from people. So it is not the case that everywhere love attracts; indeed love sometimes manifests itself as a great repulsion which brings together whole societies against a man.

`Abdu 'r-Rahman ibn Muljam was one of the most adamant enemies of 'Ali, and `Ali understood well that this man was a very dangerous opponent. Sometimes, even, others would say to him that he was a dangerous man, and that he should get rid of him. But `Ali asked in reply, "Should I punish before the crime? If he is my murderer, I cannot kill my own murderer: he is to murder me, not I him." It was about this person that 'Ali said- I want him to live; he wants to kill me.' (i.e., "I have love for him, but he is my enemy and has malevolent designs against me.")

Secondly, love is not the only healing drug for mankind; roughness is also necessary for certain tastes and temperaments, and conflict, repelling and driving away are also necessary. Islam is both the religion of attraction and love and the religion of repelling and retribution (niqmah).
