These are morsels fit for elephants, that an ant cannot swallow. What we do is similar to selling mirrors at a market place for the blind.

In his work, Fatawa-i Omariyya bi-Tariqatil-Aliyye, Omar Ziyauddîn (KS) explains the concept of rabita as affection and love towards Allah (SWT), His beloved Prophet (SAW), and the awliyaullah. Its literal meaning being to strengthen, to bind and to connect, rabita is therefore, a spiritual bond of affection that a dervish strives to establish with the beloved.

He goes onto describe its importance within Tasawwuf, which encourages one to institute such a bond and spiritual connection with ones sheikh, Rasulullah (SAW), and with Allah (SWT), so that eventually, as the dervish progresses upon this path, the strengthening of this bond will enable him seek himmah – which is help and guidance, from the one to whom he is connected to, through rabita. Furthermore, keeping rabita as often as possible, induces the dervish to remain in a state of modesty, as though he were in the presence of his sheikh, or Rasulullah (SAW), and so that he remains in awareness of Allah (SWT)…thus distancing himself from evil, and enabling one to progress spiritually.

There is a rabita of love in the hearts of believing men and women towards Allah, His Prophet, and His beloved servants (awliyaullah). Depending on their affection, love and abilities, the presence of this bond is natural and required. We can observe it in the lives of the companions of the Prophet (SAW). Every believer must connect his heart to the heart of the Prophet with a link of light, and try to receive inspiration and enlightenment from Rasulullah (SAW) through that link.
Omar Ziyauddîn (KS)

Omar Ziyauddîn (KS) further draws attention to the fact, that this bond of love and affection occurred naturally in the hearts of the sahaba (the companions of the Prophet), the tâbi'în (those who saw the companions), and the taba-i tâbi'în (those who saw the tâbi'în). However, due to the long time that has passed since the age of the Prophet (SAW), and the tarnish which has collected within men’s hearts, it is inevitable that their love for Rasulullah (SAW) has decreased.
This is why the khalifah of Rasulullah (SAW) and the awliya have always requested their disciples to keep their hearts clean; by forsaking unnecessary occupations, engaging in matters of spiritual value, and spiritual development, as well as encouraging them to engage in rabita.
In his work, Ihyâu Ulum'id-Dîn Imam Ghazali wrote:

"When you recite at-tahiyyat prayer, imagine the Prophet (SAW) and say 'As-salâmu alayka ayyuhan-nabiyyu wa rahmatullàhi wa barakâtuhû.' Also imagine that your greeting has reached the Prophet and he responded: 'Wa alaykumus-salâm wa rahmatullàhi wa barakâtuhû.”
