Maniacal tendencies refer to desires that become excessive, unreasonable, coercive, and violent. Severe forms of mania can be dangerous. To prevent maniacal tendencies, one should introspect to determine how reasonable and important their desires are, and whether fulfilling those desires could harm others. Practicing NAMASMARAN, which involves remembering God, can help avoid disasters caused by maniacal tendencies, even for those without religious beliefs.
