Sutra:
235. avanai ivan paRRum paRRu ahankAra garbham; avadhyakaram.
236. avanudaiya SveekAramE rakshakam.

Sri PBA Swami's Sarartha Deepikai:
It is shown that the surrender done with the idea that it is the means is a bad thing.

If the chetana who looks to Him, who offers protection without any cause, performs the surrender for himself, then that act is done with ego and it is as shameful as a son demanding that a father sign a contract.

Then, what is the chetana's protection? He is responsbile for the protection of the chetana. Therefore, it is in His desire to protect the chetana that the chetana takes protection.
