Keval gyan could be achieved only in the presence (by darshan) of a livingTirthankara, and without Keval Gyan, no ultimate stage of liberation - Moksha could be arrived at.

After Self-Realization one should truly know about Simandhar Swami and pray to him with proper intent in order to achieve ultimate salvation - Moksha.
