(Mutsawwif). The one who pretends to have mystic knowledge. Through such pretence the mutsawwif becomes a danger to himself and others. While being held firmly in the grip of his own lower self, this pretender alleges that he can guide others to their Higher Self. The seeker must be on the alert when searching for an authentic Spiritual Guide. When the actions and words of the mutsawwif are weighed in the Scale of the Sacred Law and when his conduct is measured against the 'beautiful model' of the Holy Prophet Muhammad it is easy to discern that he is a fraud.
(Khalwa). The spiritual retreat and seclusion. Initially seclusion is undertaken by physically withdrawing from those outside disturbances which have the potential of distracting one in his contemplation of Allah's Names and Attributes. Ultimately this withdrawal becomes purely spiritual when the heart is in a state of perpetual presence with Allah . Then the lover of Allah is with his Beloved at all times, regardless of the external conditions within which he is situated. Seclusion is the conversation of one's secret awareness with Allah. This is known as 'Khalwa fi Jalwa' (Seclusion within society) - as you are in a private state of seclusion with Allah while going about your everyday activities.
(Ikhlaas). Sincerity and purity of intention. Without this noble quality man is unable to advance towards his Lord or live in harmony with the creation. With it he is able to traverse great distances and attain to great heights of knowledge. The core of ikhlaas is the purification of the intention to the highest degree. It is the 'eye' of the intention.
A man must ensure that his sincerity is only directed towards Allah, since a man may be sincere in his devotion to the Devil as well. Imam al Junayd said that "Ikhlaas is to speak the truth when only a lie will save you".
Dhun Nun al Misri said "Truthfulness is the sword of Allah, it is never put on anything but it cuts it through".
Abu Ya'qub asSusi said "If they have witnessed the sincerity in their sincere actions, then they need to be sincere in their sincerity".
It has been said that the hardest thing for the ego is sincerity because he does not have any part in it. The difference between ikhlaas and truthfulness is that truthfulness is the tree and sincerity is the branch. Sincerity can only be manifested by entering the realm of actions.
(Jalwa). The knower ('Arif) is the one who observes the spiritual retreat (Khalwa) while being engaged in everyday activities within society (Jalwa). During such a time, when he is present with Allah, he finds inexpressible sweetness (Halawa). Such a lover of Allah is also called 'one who is engaged and yet is free' or 'busy/not busy'.
