Beyond simple bliss, what does the text define as the 'supreme attainment' gifted by Sai?

The 'supreme attainment' gifted by Sai, as explained in Chapter 1, is a profound and constant state of being rather than a fleeting emotion. It is described as a 'joyful disposition' characterized by peace, joy, and satisfaction in the heart at all times. This disposition is rooted in the personal, experiential realization that 'Brahman is truth' and 'The world is an illusion.' Sai is presented as the very source or 'mine' of this joyful state. Therefore, the supreme attainment is not just an idea but a lived reality of constant, blissful awareness, where the devotee is always full like the ocean with supreme bliss.
