I know Silabatta Parāmāsa has been talked about with various explanations, almost like there’s a wrong grasp of Silabatta Parāmāsa and its meaning. 
The most crystal clear explanation is of course found in the suttas: DN33
Five emotional shackles:
They lead the spiritual life hoping to be reborn in one of the orders of gods, thinking: ‘By this precept or observance or mortification or spiritual life, may I become one of the gods!’ This being so, their mind doesn’t incline toward keenness, commitment, persistence, and striving. This is the fifth emotional shackle.
Perfect explanation of Silabatta Parāmāsa.
