Answer

In Jain philosophy, dravya means substance or reality. It is that which has existence, qualities (gunas), and modes/changes (paryayas).

Explanation

According to Jain thought, the universe is made of eternal substances called dravyas. These substances do not get created from nothing and do not become absolutely destroyed; they only change their forms or states.

The main dravyas are generally described as:

• Jiva — the soul, living substance
• Pudgala — matter
• Dharma — medium of motion
• Adharma — medium of rest
• Akasha — space
• Kala — time

Each dravya has its own nature:

• It is real
• It has qualities
• It undergoes change
• It remains itself despite change

Spiritual Understanding

Understanding dravya helps a Jain seeker see the difference between:

• the soul and matter
• what is eternal and what is changing

This is important because liberation in Jain Dharma comes from knowing the true nature of the jiva and freeing it from attachment to pudgala.

Takeaway

In simple words, dravya is the fundamental substance of reality in Jainism. It is the base of all existence, and understanding it is the first step toward right knowledge.
