செப்பு, மூடியோடு சேர்ந்து இருப்பதுபோல் உட்பகை கொண்ட குடும்பமும், கட்சியும், அரசும் வெளியே சேர்ந்து இருந்தாலும் உள்ளத்துள் சேரவே மாட்டா.

செப்பு எனப்படும் சிமிழில் அதன் மூடி பொருந்தியிருப்பது போல வெளித்தோற்றத்துக்கு மட்டுமே தெரியும் அவ்வாறே உட்பகையுள்ளவர்கள் உளமாரப் பொருந்தியிருக்க மாட்டார்கள்

செப்பின் இணைப்பைப் போல புறத்தே பொருந்தி இருந்தாலும், உட்பகை உண்டான குடியில் உள்ளவர் அகத்தே பொருந்தி இருக்கமாட்டார்.

Never indeed will a family subject to internal hatred unite (really) though it may present an apparent union like that of a casket and its lid

Kural 887 addresses the concept of unity and its importance within a family or a group. The verse uses the metaphor of a casket and its lid to illustrate a false union. Just as a casket and its lid might seem to be in perfect cohesion on the outside, they are not inherently unified as they are separate entities. Similarly, a family or group might present a facade of unity externally, but if there is internal discord, the unity is merely superficial and not authentic. The verse emphasizes that a family or group tainted by internal strife or hatred can't truly unite, despite appearances. The presence of mutual animosity and resentment prevents a genuine bond or connection from forming. The unity, in this case, is superficial and is unlikely to withstand the test of time or adversity. This verse underscores the importance of harmony, understanding, and mutual respect within a family or a group. It suggests that true unity is not just about outward appearances but is about forming deep, meaningful bonds based on mutual respect and shared values. It serves as a reminder that internal discord can undermine the strength and stability of a family or group, regardless of how united it may seem externally. In a broader context, this verse can also be applied to communities, societies, and nations. It suggests that a society riddled with internal conflicts, despite presenting a united front, will struggle to maintain peace and progress. Thus, the verse advocates for the resolution of internal conflicts and the promotion of unity for the overall well-being and progress of a family, group, or society.
