What is masturbation, and what is the difference between it and a wet dream? Does a wet dream occur while awake? Is the emission of something considered either a wet dream or masturbation? Are there religious and health risks in both of them?

Masturbation is the deliberate expulsion of semen by hand or other forms of sexual perversion, whereas a wet dream is what occurs during sleep. A person should avoid thinking about such matters so that nothing is discharged from him, and should occupy himself with beneficial things. If something is discharged, then he should ascertain whether it is prostatic fluid (madhy) or semen (mani).
