Can you elaborate on the symbolic meaning of 'Seemollanghan' as taught by Sai Baba in the context of his own passing?

Sai Baba used the Dussehra festival to teach the profound spiritual concept of 'Seemollanghan,' which is the crossing of a border. In this context, it symbolized transcending the ocean of worldly existence. Chapter 42 explains that Baba didn't just teach this as a metaphor; he provided a living demonstration. He chose the auspicious day of Dussehra in 1918 to perform his own ultimate 'Seemollanghan.' By offering his body to the fire of Yoga and merging with the Supreme on this day, he transformed a festive pretext into a powerful, experiential lesson on transcending life and death, making it the true auspicious moment for his departure.
