In order to make its point about the spiritual essence of everything that exists, the Gita continues to provide examples that illustrate that the essential and defining energy of each thing is what can be traced to the Divine Presence. The outer forms are the occasion for this manifestation, and they are in fact formed and created by that Power in order to provide a vehicle for the force to manifest.
Sri Aurobindo translates a verse from Chapter VII of the Gita: “I am the light of sun and moon, the manhood in man, the intelligence of the intelligent, the energy of the energetic, the strength of the strong, the ascetic force of those who do askesis, tapasya.”
It becomes even more starkly defined: “I am life in all existences.” Sri Aurobindo explains: “In each case it is the energy of the essential quality on which each of these becomings depends for what it has become, that is given as the characteristic sign indicating the presence of the divine Power in their nature.”
“It is the essential quality in its spiritual power that constitutes the Swabhava. It is the force of spirit so manifesting, it is the light of its consciousness and the power of its energy in things revealed in a pure original sign that is the self-nature. That force, light, power is the eternal seed from which all other things are the developments and derivations and variabilities and plastic circumstances.”
“This eternal seed is the power of spiritual being, the conscious will in the being, the seed which, as is said elsewhere, the Divine casts into the great Brahman, into the supramental vastness, and from that all are born into phenomenal existence.”
The Gita here is translating the symbolic language of the Rig Veda, such as Hymn X.129 called the Hymn of Creation, or the Hymn to Hiranyagarbha, the Golden Child in the Womb. If we reflect on what a seed is in the world of manifestation, it has involved in it the entire genetic programming that makes the resulting being “what it is”. The seed of the universe is what contains within itself the knowledge, power and will to existence for the development of all forms, beings and forces in the universal creation.
