On the topic of why the companionship and guidance of a perfect guide, who is a divine scholar, are essential, Hazrat Imam Rabbani, Mujaddid Alf Thani, may his secret be sanctified, states:
“Oh honorable one!
The purpose of human life is to reach the exalted presence of the Divine.
Since a disciple [spiritual seeker] is initially entangled in various attachments, resulting in extreme impurity and lowliness, while the Divine Essence is immensely pure and exalted, there’s no alternative [for his cure] but a perfect guide (Murshid Kamil) who is knowledgeable about the path and sees it correctly.
He [Murshid Kamil] acts as an intermediary, maintaining a connection with the Divine and the ordinary human so that he becomes the means of the seeker’s attainment with the Lord.”
