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. Repeating a mantra like "namasmaran" can help avert disasters caused by maniacal tendencies by providing quiet and peace, even for those without religious beliefs.
