Sri PBA Swami's Sarartha Deepikai:
The chetana who gives up the other paths and adopts this siddhOpaya, does not become one who has given up the other paths completely. How is that?

The daily and special acts and rituals that he performs, appropriate to his varNa and Ashrama, are done not with the thought that they are the means. Instead, they are done due to kindness toward others, and therefore lead to His pleasure. Thus, they are part of the service done to Him.

The acute knowledge is that which makes the chetana realize the nature of the Supreme which then leads to the realization of the nature of the self. This knowledge, when not used as a means, belongs within the true nature of the self.

Once the thought that it is a means is given up on that bhakti which leads to the Lord, it becomes part of the taste (the desire) that comes just prior to service to the Lord, just as hunger precedes eating.

As mentioned in the 'Eka' term, prapatti (which is acceting the Lord Himself as the means), if itself is not thought of as the means, belongs to the true knowledge of that self which has no other refuge and is solely dependent on the Lord.

Therefore, it is right to say that the chetana has not given them up completely.
