The tense of the verb ('reads') is appropriate for an action habitually performed. In English texts, the article 'the' is frequently used before the title of the work. Using the definite article 'the' before the title of a sacred or revered work (a "holy book") is common: the Bible, the Koran, the Torah, the Vedas, the Tripitaka etc. Also certain widely known books or works, e.g. the Encyclopaedia Britannica, the A-Z Road Atlas of London, the Canterbury Tales.
The Ramayana originated in north India as an oral epic poem, performed
with musical accompaniment and dance. Written, illustrated manuscripts
of the poem were later produced from Pakistan to Indonesia. This means
that the Ramayana has expressions in oral performance, dance, music,
literature, and illustration.
