SB 11.25.17
vikurvan kriyaya ca-dhir
anivrttis ca cetasam
gatrasvasthyam mano bhrantam
raja etair nisamaya
Translation:
You should discern the mode of passion by its symptoms — the distortion of the intelligence because of too much activity, the inability of the perceiving senses to disentangle themselves from mundane objects, an unhealthy condition of the working physical organs, and the unsteady perplexity of the mind.
