Answer

Halaradu ke 2nd stanza mein Siddhashila ka paryavachi naam “Mokshashila” mana jata hai.

Explanation

Jain Dharma mein Siddhashila vah param sthaan hai jahan moksha prapt ki hui atmaen, yani Siddha Bhagwan, hamesha ke liye virajmaan rehti hain.

Isliye usse Mokshashila bhi kaha jata hai, kyunki vah moksha prapt atmaon ka nitya sthaan hai.

Takeaway

Siddhashila = Mokshashila, arthaat moksha prapt Siddha atmaon ka shashvat sthaan.
