I feel lost since Baba is no longer physically present. How do his teachings help overcome this feeling of separation?

The wisdom from Chapter 43 offers great solace for this feeling of separation. It encourages us to see beyond the physical form. While his body is no longer present, the text reminds us that his task for the devotees was over, and he chose to merge back into the unmanifest. It asks, "Who will believe these words?" that he truly left, because he "stayed in the hearts of the devotees." The teaching is that by merely remembering his name, "no news of birth or death remains." He is not confined to the three and a half cubits of his body but fills the entire world. Chapter 43 assures us that "whatever the feeling in one's mind, such is the experience even today," meaning he continues to respond and be present for you in his true, all-pervading form.
