Answer

Yes. In Jain Dharma, the Tirthankaras of the present time cycle have attained moksha and reached Siddhashila. The last Tirthankara of this avasarpiṇī is Bhagwan Mahavira, and he too attained Siddha state.

Explanation

A Tirthankara is not a permanent being on earth. After completing their worldly life, they attain keval jnana and then moksha. After moksha, the soul rises to Siddhashila, the abode of liberated souls.

So, if by “current Tirthankara” you mean the Tirthankara of this time cycle, then:

• Bhagwan Mahavira has already reached Siddhashila.
• All past Tirthankaras of this cycle have also attained moksha.

Spiritual Understanding

This teaches an important Jain truth:

• Every soul has the potential to become liberated.
• Even the greatest spiritual teachers, after completing their role, move beyond the cycle of birth and death.
• Siddhashila represents complete freedom from karma, suffering, and rebirth.

Takeaway

Yes, the Tirthankaras of this era, including Bhagwan Mahavira, have attained Siddhashila.
