The Core of His Vision
When Mulla Sadra speaks of the Unity of Existence, he is not offering a metaphor but describing the very structure of reality. The cosmos is one Being, manifesting itself at different levels and intensities. Mountains, rivers, animals, humans, and even thoughts are not isolated things but gradations of the same underlying reality. This vision rests on three intertwined principles:
Unity of Existence – All that exists is but one Being, refracted into countless forms.
Gradation of Existence – Reality reveals itself in degrees, from the faintest mode of being to the most intense.
Dynamic Manifestation – Existence is never static but in constant renewal, a ceaseless unfolding of Being moment by moment.
In this sense, Sadra’s universe is alive, pulsing, and ever-transforming—a metaphysical dance of unity in diversity.
Implications Beyond Philosophy
The consequences of this vision stretch beyond abstract ontology. If all beings are gradations of the same reality, then separation is an illusion. This leads to:
Holistic Understanding – A cosmos where nothing is isolated, where every fragment carries the whole.
Ontological Unity – An insistence that we share a common source, making otherness less foreign and more like an echo of the self.
Spiritual Depth – A call to recognize and reconnect with the deeper unity behind appearances, which turns philosophy into a spiritual path.
Sadra’s perspective, while deeply philosophical, becomes also ethical and mystical—it reshapes how one relates to the world, to others, and to oneself.
Innovation and Resistance
Yet, Sadra’s originality came at a cost. His Transcendent Theosophy (al-Hikmat al-Mutaʿāliyah) synthesized Avicenna’s rationalism, Suhrawardī’s illuminationism, and Sufi mysticism into a single framework. Such daring integration appeared unorthodox to Islamic religious authorities. His insistence on the primacy of existence, his merging of philosophy and mysticism, and his critique of rigid scholasticism invited suspicion.
Sadra faced accusations of heresy and endured exile, but he survived to complete his philosophical system. Suhrawardī, the visionary before him who founded Illuminationist philosophy, was not so fortunate. Seen as dangerously unorthodox, he was condemned and ultimately assassinated in Aleppo at the age of thirty-six. Their fates illustrate the fragile balance between intellectual innovation and political-religious power: one forced into the solitude of exile, the other silenced permanently.
A Living Legacy
Today, Mulla Sadra’s thought continues to ripple through discussions of metaphysics, ontology, and spirituality. His emphasis on Being as a dynamic, unified reality resonates with contemporary searches for holistic worldviews that bridge science, philosophy, and spirituality. In his work, one hears both the voice of the ancient Indo-Iranic sages who spoke of cosmic and natural order, the Truth, and the modern quest for unity in an age fractured by division.
Sadra’s legacy is therefore double-edged: a reminder of the courage required to think beyond inherited limits, and an invitation to glimpse the hidden unity beneath the surface of all things. His philosophy is not only a historical system but a living orientation—a way of seeing the universe as a continuous revelation of Being.
