Ilm-i zahiri (outer knowledge) is similar to passing rainwater. As for the batini (inner) ilm, it is a treasure with a solid foundation, and this is more beneficial than the outer ilm. Allah the Most High grants as an example:

“Barren earth has to be a proof of Our power to them. We gave life to it, and raised grain from it, and they eat therefrom.” (Ya Sin 36:33)

Allah the Most High created grains in the material world, which is the strength for the animal self. He also created grains in the spiritual realm, which is the strength and nourishment for the spiritual ruhs. Our Prophet, peace be upon him, says in an honorable hadith:

“Whoever makes it to morning with ikhlas (see Ikhlas 112), springs of wisdom will flow into his tongue.”

As for the profit of the ruhu sultani, it is to gaze at the manifestation of the attribute of Jamal (Beauty) and to be in awe. Allah the Most High relates this as:

“Fuad did not deny what it saw.” (Najm 53:11)

The following hadith relates this in a different way:

“The mu’min (believer) is a mirror of Mu’min.”

What is meant by the first mu’min is the heart of the believing servant of Allah; by the second Mu’min, what is meant is Allah the Most High, Himself. Allah the Most High tells us one of His attributes is Mu’min thus:

“He is Mu’min and Muhaymin (The Protector).” (Hashr 59:23)

The residence of the ruhu sultani is the third paradise, Firdaws. As for the place of the action and station of the ruhul quds (the holy spirit), it is the sirr (secret). The nature of this spirit is told in the following hadith:

“The human being is My secret and I am his.” [I am hidden in the human being and he is hidden in Me.]

The merchandise of this spirit is ilm-i haqiqa (knowledge of the truth or reality). This ilm is at the same time the knowledge of tawhid (unity; oneness).

What it does is continuously make zikr (remembrance) of the names of tawhid. This process is carried out through the language of the secret. There is no outer articulation as in the other languages.

“If you say it aloud (or not), he surely knows the sirr (secret), and that which is akhfa (the most hidden; secret of secret).” (Ta Ha 20:7)

These are two places in the heart. Only Allah knows the situation of this spirit.

The profit of this spirit is the attainment of the spiritual baby. What it sees and observes is the countenance of Allah the Most High. It gazes at both the attributes of Jalal (Power) and Jamal (Beauty).

This observation is through the eye of the secret. In this way faces gaze, glowing, at their Lord. No comparison can be made there. He [Allah] sees and hears.

When a person finds his goal, he falls under the management of aql (intelligence; mind; the power of understanding and discrimination). Hearts go in awe. Tongues are fettered; he cannot find the strength to relate these situations. The reason for this is that Allah is beyond the examples seen.

The above quote is from this book:

So, this experience starts now to come into focus. It seems in 1982 this attainment, this flight of the spiritual baby was granted for me, happened in me and becomes me.
