The Throne's Horizon — Sama, Arḍ, and the Body of Meaning

Mapping Rizq and Neurological Integration from Kursī to the Inner Cosmos 

---

Introduction

Following our exploration of the word Kursī as a symbol of divine governance and neurological centrality, we now move to the verse that frames it: "Wasi’a kursīuhu al-samawāti wa al-arḍ" — "His Kursī extends over the heavens and the earth" (Qur'an 2:255). This cosmic statement demands an inward reflection: what does it mean for something to extend over both sama and arḍ? What are the implications when viewed through the inner lens of embodiment, cognition, and divine energy?

Sama: Elevation and Perception

In the Qur'anic structure, sama (heavens) often symbolizes elevated knowledge, divine decree, unseen forces, and perception. In the body, this can be mapped to the higher faculties of the mind: cognition, imagination, and spiritual consciousness. The root "s-m-w" implies height and sublimity. This is the realm where names like Al-Samīʿ (The All-Hearing) and Al-Salām (The Source of Peace) govern. Sound, peace, perception: all elements that activate the upper spectrum of the nervous system.

Neurobiologically, the sama may correspond to cortical and prefrontal areas — the seat of decision-making, abstract reasoning, and receiving the "signal" of divine inspiration. This connects to the heavenly dimensions of wahy (revelation), which the Qur'an itself describes as "descending" from the unseen realm.

Arḍ: Grounding and Manifestation

The arḍ (earth) is the field of action, manifestation, nourishment, and gravity. It represents what is known, measurable, and experienced. Linguistically, its root (‘-r-ḍ) signifies breadth and support — it carries, holds, and sustains.

In the body, arḍ refers to the physical matrix, the somatic field. It includes our grounded experiences, digestion, respiration, and physical reflexes. It is also the realm of rizq (sustenance), which Imams have said lies in the fourth heaven — a mysterious reference we will revisit below.

Kursī as Interface: The Role of the Thalamus

Between sama and arḍ lies the Kursī — a throne not resting above, but stretching across. It integrates the high and low, the subtle and the gross. In terms of human neuroanatomy, the thalamus becomes a powerful candidate for this role.

The thalamus sits at the center of the brain and acts as a relay station between the sensory input (body/earth) and the cortical centers (mind/heavens). It is the seat of regulation, of conscious attention, of data integration. It links the sama of meaning and perception with the arḍ of action and reaction.

Here, we introduce the Name Al-Razzāq (The Provider) — tied deeply to thalamic function. Rizq in this context is not just food or money, but insight, integration, and the capacity to receive. Rizq is what comes when the system is open, centered, and attuned. The fourth heaven, then, may refer symbolically to the fourth energetic or neurological gateway — neither physical nor purely spiritual.

The Root Letters: Ka, Ra, Seen

In Kursī, we find three key letters:

• Kāf (ك) — Power, containment, potential

• Rā (ر) — Movement, divine command, flowing energy

• Sīn (س) — Clarity, vibration, signal

From Kāf we get Kabīr (The Great) — the overarching presence. From Rā: Razzāq, Raḥmān, Raʻūf — all Names involving flow, giving, mercy. From Sīn: Samī’, Salām, Ṣabūr — peace, patience, perception.

These Names show the anatomy of the Kursī: power (k), distribution (r), and sensitivity (s). The Kursī becomes the throne of distributed intelligence — governing by balancing reception, movement, and stillness.

Conclusion: The Inner Sky and Earth

When Allah says the Kursī extends over the heavens and the earth, He is describing not just a cosmological domain, but also a system of inner calibration. The throne is the integrator. And when aligned, rizq flows, the body becomes aware, and the heart becomes soft. This is the divine interface that every human contains.

In our next post, we will turn to the Hadith traditions to explore how the Prophet and the Imams spoke about the nature of governance, expansion, and the seat of command — and what they reveal about the inner meanings of the Kursī.
