Nāma‑karma = the “form‑making” karma of the soul.

Very simple idea Just as:

• a mould gives shape to molten metal, or
• a blueprint decides how a house will look,

in the same way nāma‑karma decides the “design” of your next life.

What does nāma‑karma do?

Due to nāma‑karma, the soul gets:

• which gati (state) – human, animal, heavenly, or hellish
• which body type – number of senses, strength of body, beauty/ugliness, height, colour, etc.
• many other physical and external features

So:

• Ghātiyā karmas (like jñānāvaraṇa, mohanīya, etc.) disturb the inner qualities of the soul (knowledge, faith, conduct).
• Nāma‑karma is aghātiyā karma – it does not damage the pure qualities of the soul, but it decides the outer package in which the soul will live.

Easy analogy

Think of the soul as clear light.

• Nāma‑karma is like different coloured and shaped glass placed around that light.
• The light itself is always pure, but because of the glass, it appears:

- red or blue (colour/complexion), - big or small (size), - beautiful or ugly (form), - human, animal, deva, or nāraki (type of body and existence).

When nāma‑karma is finished (destroyed), the soul’s pure light shines without any outer covering – this is the state of Siddha.
