Pure states must be in accord with the Shari'ah so that the faqir does not harm any one of the People. The faqir who does not have the states does not reach the Stations of the Men. Travel to the presence of the Perfectly Pure does not occur except by going against the self. It says in the Hikam, 'Were it not for the battlefield of the selves, meaning war on it, the travel of the traveller would not be realized.' In this instance, states mean breaking the habits of the self and the destruction of its outward. The faqir must practice what will diminish the self and obliterate its might. The practices must be permissible. These are the pure and pleasing states. States that are contrary to the Shari'ah, and these are the states of darkness, only increase the man who has them in darkness. In the same way that it is not proper to bury seeds in bad land, it is also not permissible to bury the self in obscurity in a displeasing manner. Pure states are those in which there is no harm for anyone and which are not contrary to the order of the Shari'ah.
