His Philosophical Vision 

When one has studied the foundational texts of a school of philosophy, naturally one's own philosophy would also be much influenced by these works. It was a fortunate set of circumstances that helped him to delve deeply into some of the basic texts of Nyaya. In particular, he analysed each sentence and even each word in the Isvaravada section of Gangesa's Tattvacintāmaṇi. The wider implications of the explanations and argumentations developed in this text began to dawn upon him quietly and consistently. Why is it that according to Nyaya logic, it is possible to establish the existence of God while in the Buddhist logical system it is not possible to establish the existence of God? An adequate answer to this question lies in the concept of knowledge of the different systems leading to different kinds of understanding of human beings themselves. Thus Nyaya system has as horizon a theory of knowledge which renders possible the discourse about God; it could even be asserted that according to Nyaya, the Absolute becomes the horizon of all knowledge and therefore also of all human activities.

Such an understanding of Nyaya helped him to develop his own philosophy. A human being can be fully understood only if his metaphysical relation with the Absolute is accepted as a constitutive principle of his very being. In other words, an integral humanism calls for transcendence.  Such a view naturally rejects a purely empiricist understanding of a human being. This means that the fullness of being human can be achieved only in and through the transcendent. This is because the transcendent remains not only at the theoretical level but at the actual existential plane the center of human beings and hence it invests human life with a unique value and significance not confined merely to the world that is experienced by the senses. However, this world is not denied; it has its value. It is in and through this world that transcendence operates. Therefore, being human is being fully immersed in this world and fully in the transcendent. Hence to present a humanism without placing the transcendent at its center is to impoverish human beings; it will be the greatest injustice to them.

But concretely, what  is the nature of this transcendence? In order to grasp this and to develop his original view of it, the Advaita Vedanta of Sankara especially as interpreted by the late Richard De Smet has been very helpful to him. De Smet rejects the all too common acosmic interpretation of Sankara and asserts that the true nature of the Supreme Brahman as person, ultimate cause, capable of love and grace. Therefore, the highest Brahman is more than a vast ocean of pure consciousness, but in such a way that the simplicity, plenitude and transcendence of the divine are in no way compromised. It is clear that here non-duality (advaita) is read as a doctrine of creation rather than as a teaching of illusionistic monism. The Supreme Brahman is also a person in a pre-eminent sense. The concept of person in itself does not involve any limitation and hence Brahman considered even in the strict Advaita perspective of Sankara's Vedanta is most properly and eminently personal, indeed the Super-person.

This Brahman or God can be described in many ways, but chiefly in the negative, the superlative, the world-relational, the ego-relational and the essential manner.  The negative description differentiates God from all other reals by stating that it is not so, it is not so (neti neti). Such description teaches us that no term or concept can express God properly because the expressive power of terms and concepts is restricted to the empirical and hence it denies all idea of finitude in God. Asserting absolute transcendence of God, saving our mind from all temptations of pantheism, this description leads us to apophatic theology. The superlative portrayal of God accounts for the negative description. Because God is Fullness of Being, supreme in every regard He is unlike anything finite. God is the Fullness (purna) of all illimitable perfections; He is the very fullness; He is intensive fullness, not fullness by addition. He is thus the most desirable, the supreme value. He is homogeneous goodness (ekarasa). We have no example of such fullness in our experience. Yet all the beings we know directly have a relation of similarity to God and they can enrich our idea of God. The world-relational definition of God asserts that he is the sole cause of the universe. God provides both the reality and the orderly structure and course of the universe. But this does not imply any change in God; He just gives reality and order from its own fullness. Such a causality of God is so universal and ontologically complete that it is the innermost self of every single entity. The ego-relational description of God operates with reference to the knowing individual self. Each one knows from one's own experience that the ego is agent, enjoyer and knower, but its tadatmya relation with God is not known. The fundamental nature of the self is its relationship with God. And God being the innermost self of man, the former imparts his luster to the individual even to his body and organs especially the intellect. The final description of God is essential. God's essence, is truth, knowledge and being infinite. The two terms reality and knowledge together indicate that in God there is no distinction or composition.

In Sankara the external world is described as upadhi, translated usually as limiting adjunct. But nobody really explains what it really means.  He interprets it with reason as symbol;  the world is a symbol of God - this is the thought of the only real poet theologian in the Christian tradition, St. Ephrem, a fourth-century saint who lived and worked in Nisbis and then in Edessa. The Supreme reality is communicated to us in the universe which is a vast assembly of symbols singing the goodness of God and this is his philosophy. Infinite are the possibilities of developing this line of thought inspired by the intuitions of Sankara and Ephrem.
