Yes—this is broadly correct in Jain philosophy.

Darshan means the non-specific, general awareness of an object, without detailed discernment. It is a kind of mere apprehension or awareness before differentiation.

Upayog means the active functioning of consciousness. In Jainism, it includes both:

• Darshan upayog — general awareness / perception
• Jñān upayog — specific knowledge / cognition

So, in Jain soul theory:

• The soul’s inherent nature is consciousness
• This consciousness expresses itself through darshan and jñān
• Upayog is the practical manifestation of that conscious activity

This is indeed a very important point in Jain karma and soul doctrine, because karma covers and obstructs the soul’s natural powers of perception and knowledge.

In short:

• Darshan = first, general, non-specific awareness
• Upayog = consciousness in action, including darshan and jñān

Your understanding is aligned with Jain philosophical teaching.
