Can you explain the philosophical concept discussed in Chapter 31 regarding the moment of death?

Chapter 31 elaborates on the critical importance of one's state of mind at the time of death. It posits that whatever a person meditates upon in their final moments is the very form they will attain in their next life. To ensure one's thoughts are focused on God and not worldly confusion, the chapter recommends the continuous practice of remembering the divine Name. This practice, along with satsang or surrendering to saints, is crucial because saints are said to understand the process of life and death and can guide a soul to liberation, ensuring a lifetime of devotion is not wasted at the very end.
