What we saw so far was the first half of the shloka.
In the second half our Acharya gives the definition of Bhakti:
Bhakti is said to be the unbroken union with one’s own natural Self – the Atman.
*bhaktiH iti abhidhIyate* means ‘it has been named bhakti’.
Do ‘anusandhAnaM’ of one’s own natural state, says he.
What is ‘anusandhAnaM’?
*sandhAnaM* means a unification or joining with something. A meeting’!
If that union stays continuously, it is ‘anusandhAnaM’.
