The meaning of this word, too, is not entirely clear. Literally, Shila means stone. According to dictionaries, Shila (or Sila) carries meanings such as stone slab, rock, boulder, threshold, armor, or character. The word Shil or Sheel also means virtue, moral conduct, or character.
Although it is uncertain which exact sense was intended when adding this term to gotra names, the moral and ethical connotation of the word seems significant. Sheel (virtue, morality) represents the noble qualities and righteous conduct of a person. It is possible that the term Shila or Sila was used as a symbolic representation of these virtues — integrity, character, and moral strength. Over time, Shila and Sila might have become common or colloquial forms of the same word.
In conclusion, the words Malla, Shri (Sira/Siri), and Shila (Sila) appear to have been attached to the gotra names of the Perika community to convey deeper meanings. Malla reflects their ancestral warrior lineage, Shri symbolizes auspiciousness and prosperity, and Shila represents virtue and moral character. Regardless of the specific gotra name, it seems that one of these three meaningful suffixes was often added to make the name spiritually and culturally significant.
