How can a devotee recognize the awakening of the Guru's grace within themselves? Are there specific signs?

According to Chapter 27, the awakening of a Guru's grace manifests through distinct physical and emotional experiences that are beyond the reach of ordinary senses. When listening to the Guru's stories, a devotee might experience perspiration, eyes filling with tears of love, a captivated life-force, and a moved heart. The text also describes goosebumps rising repeatedly, along with frequent weeping and sobbing. These profound reactions, which also include the destruction of mutual conflicts and the vanishing of distinctions between small and great, are considered signs that the Guru's grace is at work. The chapter emphasizes that these eight sattvic emotions do not arise without ultimate faith in the Guru's feet.
