Sutra:
27. palamirukkumpadi pramEyasEkaraththilum arcchirAthigathiyilum sonnOm.

Meaning:
The end result of the goal seeked by souls has been explained by Sri Pillai Lokacharya shortly in the rahasya grantha Prameya Sekharam and in detail in the rahasya grantha Arcchirathigathi.

Sri PBA Swami's Sarartha Deepikai:
In the previous sutra, in showing the meanings of the words that make up the Thirumanthra, it was said that Narayana shows the result of the goal seeked. If one wishes to know the details of what this result is, which starts from attaining mOksha and ends in earning His eternal service, it has been explained in two rahasya granthas - in short in Prameya Sekharam and in detail in Arcchirathigathi.
