What is the philosophical understanding of a saint's death, like Sai Baba's, according to the provided text?

According to the teachings in Chapter 43, the death of a saint like Sai Baba is not an end but a misconception born from a limited perspective. The text compares it to a solar eclipse, which is described as a 'defect of vision' rather than the sun's actual demise. For a being like Sai Samarth, who is considered the 'complete Supreme Brahman,' birth and death are 'false imaginations.' His departure was a voluntary act where he 'burned the body in the fire of Yoga' and merged into his unmanifest, eternal state, all while remaining present in the hearts of his devotees. Death is seen as a characteristic of the physical body, which for a Yogi is merely an adjunct he has already transcended.
