Who was Soma in this shloka? Is it Rudra or someone else?
Rig Veda IX.96.5
सोमः पवते जनिता मतीनां जनिता दिवो जनिता पर्थिव्याः |
जनिताग्नेर्जनिता सूर्यस्य जनितेन्द्रस्य जनितोत विष्णोः ||
Father of holy hymns, Soma flows onward the Father of the earth, Father of heaven: Father of Agni, Sūrya's generator, the Father who begat Indra and Viṣṇu.
Soma, the Counterpart of Agni. Every form of Agni has a corresponding form of Soma, without which it cannot function properly. This is also an important fact to carefully consider. Soma is the principle of water, nourishment and bliss that complements Agni as fire, purification and knowledge. Similarly, Agni is the Sun and Soma is the Moon, the active and receptive aspects or electrical and magnetic forces, and all such complementary principles in nature. The entire universe is of the nature of Agni and Soma.
Soma is called “nectar” or amrita. As amrita means both nectar and immortality, Soma is also called the “nectar of immortality.” Soma flows in drops called bindus in Tantric thought.
As Agni is the fire that ascends from below, Soma is the grace that descends from above. Agni relates to the Kundalini fire that ascends from the root chakra below and Soma is the corresponding nectar that descends from the thousand-petal lotus of the head above in higher Yoga practices. The thousand-petal lotus is often called the seat of Soma or the Moon.
In the later part of literature, Soma was also thought of combination of Sa (Shiva) and Uma (Shakti).
