In the wiki article, it was stated as follows:
In terms of theology, Ramanujacharya puts forth the view that both the Supreme Goddess Lakshmi and Supreme God Narayana together constitute Brahman - the Absolute. Sri Lakshmi is the female personification of Brahman and Narayana is the male personification of Brahman, but they are both inseparable, co-eternal, co-absolute and are always substantially one. Thus, in reference to these dual aspects of Brahman, the Supreme is referred to in the Sri Vaishnava Sampradaya as Sriman Narayana.
My question is - Where were Lakshmi & Narayana mentioned separately or together, as God Heads, in the Rig Veda ?
I am not expecting answers referring to The Khilāni hymns, or Appendices to Rig Veda
