In the case of the intellect also this is what we did.
It was said that the intellect should be established and rested in shuddha-brahman; but intellect cannot approach anywhere near shuddha-brahman and so we understood it to mean that the intellect should dwell on matters or teachings or the Shastras pertaining to Brahman.
In the same way here also, to say that one should do ‘anusandhAnaM’ on the Nature of the Atman, is only to mean that the ‘anusandhAnaM’ (being in continuous union with the Atman) is of the thoughts about the Atman.
This anusandhanaM begins well before sannyAsa. But it is further strengthened and deepened after sannyAsa and in due course the sAdhaka gives himself up totally, and the Atman alone shines thereafter.
Continuous fusion or merging is certainly the Bhakti out of Love.
