If the illusion does not dissipate from the Guru, or if the delusion does not vanish from him, then know that Guru to be false; delay will not bring release.

Kabir delivers a powerful, sobering message here. The core insight is that spiritual realization requires complete internal purification. If the guidance received from a guru fails to dispel the illusion or the fundamental delusion within the student, then the entire teaching structure is flawed. Kabir warns us that blindly accepting any authority without personal verification of truth is merely a delay from true liberation. This is a profound call for self-reliance in spiritual questing.
