And the description of this nature is found in Balacharitha by Bhasa in Sanskrit in a Drama form.This description is found in Harivamsa too.Following are the relevant lines in Silappadikaram.
One is Bhakthi tinged with Reason and Intellectual approach.
Another is total emotional immersion in the Love of God.
And example of an intellectual bhakti may be discerned in Kalidas's first sloka of Raghuvamsa , which set about describing the Dynasty of Lord Rama.
Curiously the work that is about to talk about Lord Hari,Vishnu , begins with a Sloka on Lord Shiva and Parvathi.
This is the sloka.
The genius of Kalidasa lies in that this poem is open for Twenty Five meanings!
