Answer

In Jain usage, Kul Koti means the different categories or varieties of “kul”. Here, kul means a family or clan into which a living being is born due to gotra karma, and kulakoti refers to the many classifications of those kuls. In a traditional explanation, it is also used to indicate a very large number of such family categories. ( jainqq.org)

Explanation

A simple way to understand it is:

• Kul = family / clan / birth-group
• Koti = category, variety, or countless number in this context

So Kul Koti is about the many kinds of family lineages seen among living beings in Jain classification. One Jain text explanation says that beings born in the same yoni can still belong to different kuls, and the categories of those kuls are called kulakotis. ( jainqq.org)

Spiritual Understanding

This teaching shows the Jain view that life is highly diverse, and that birth and classification are influenced by karmic causes such as gotra karma. It reminds us that all living beings are part of a very detailed karmic order, and therefore compassion and non-violence should extend to all jivas. ( jainqq.org)

Takeaway

Kul Koti = the many kinds of family categories or clans in Jain classification, linked with gotra karma. ( jainqq.org)
