The seeker must also be trained to prevent the corruption of those good deeds which have accrued to his or her credit by overcoming the traps of ostentation, pride, arrogance, envy, and long hopes (meaning the hope for a long life allowing us to mend our ways later, rather than immediately, here and now). Sufi practices, while attractive to some, are not a means for gaining knowledge. The traditional scholars of Sufism hold it as absolutely axiomatic that knowledge of God is not a psychological state generated through breath control. Thus, practice of "techniques" is not the cause, but instead the occasion for such knowledge to be obtained (if at all), given proper prerequisites and proper guidance by a master of the way. Furthermore, the emphasis on practices may obscure a far more important fact: The seeker is, in a sense, to become a broken person, stripped of all habits through the practice of (in the words of Imam Al-Ghazali) solitude, silence, sleeplessness, and hunger. Dhikr Dhikr is the remembrance of Allah commanded in the Quran for all Muslims through a specific devotional act, such as the repetition of divine names, supplications and aphorisms from hadith literature and the Quran. More generally, dhikr takes a wide range and various layers of meaning. This includes dhikr as any activity in which the Muslim maintains awareness of Allah. To engage in dhikr is to practice consciousness of the Divine Presence and love, or "to seek a state of godwariness". The Quran refers to Muhammad as the very embodiment of dhikr of Allah (65:10–11). Some types of dhikr are prescribed for all Muslims and do not require Sufi initiation or the prescription of a Sufi master because they are deemed to be good for every seeker under every circumstance. The dhikr may slightly vary among each order. Some Sufi orders engage in ritualized dhikr ceremonies, or sema. Sema includes various forms of worship such as recitation, singing (the most well known being the Qawwali music of the Indian subcontinent), instrumental music, dance (most famously the Sufi whirling of the Mevlevi order), incense, meditation, ecstasy, and trance. Some Sufi orders stress and place extensive reliance upon dhikr. This practice of dhikr is called Dhikr-e-Qulb (invocation of Allah within the heartbeats). The basic idea in this practice is to visualize the Allah as having been written on the disciple's heart. Muraqaba The practice of muraqaba
