No. An abhavya jīv cannot have śukla leśyā.

Very simple reasoning from Jain siddhānt:

1. Who can have śukla leśyā?

- Śukla leśyā (pure white leshyā) arises only in very high spiritual stages (upper guṇasthān), where: - intense passions (kaṣāya) are almost finished, - right faith, right knowledge and right conduct are firmly established, - the soul is on the direct path to kevaljnān and mokṣa. - Such stages are possible only for a bhavya jīv (one who is capable of liberation).

1. Nature of abhavya jīv:

- Abhavya = a soul that will never get samyak darshan and never progress to moksha. - It may wander in saṃsār with various leshyās (mostly the lower ones), but it never reaches those very high states where śukla leśyā appears.

1. Therefore:

- Since śukla leśyā is tied to advanced spiritual purity and abhavya jīv can never reach that level, - By definition, an abhavya jīv cannot possess śukla leśyā.

Both Śvetāmbara and Digambara traditions agree on the basic points:

• Abhavya = forever incapable of moksha.
• Śukla leśyā = found only in extremely elevated spiritual stages leading to moksha.

So their combination is not possible.
