Muṣitasmṛtitā

Muṣitasmṛtitā (Sanskrit; Tibetan phonetic: jengé) is a Buddhist term that is translated as "forgetfulness". In the Mahayana tradition, muṣitasmṛtitā is defined as forgetting or losing our focus on a virtuous object and instead focusing on an object or situation that causes non-virtuous thoughts or emotions to arise.

Muṣitasmṛtitā is identified as:
 * One of the twenty secondary unwholesome factors within the Mahayana Abhidharma teachings

Definitions
Mipham Rinpoche states:
 * Forgetfullness [muṣitasmṛtitā] is to be unclear and forget a virtuous object. It is the erroneous mindfulness that accompanies a disturbing emotion, and it is the opposite of being mindful. It forms the support for distraction of mind.

The Abhidharma-samuccaya states:
 * What is forgetfulness? It is fleeting inspection which is simultaneous with and on the same level as the emotions. It functions as the basis of distraction.

Alexander Berzin explains:
 * Forgetfulness (brjed-nges). Based on recollection of something toward which we have a disturbing emotion or attitude, forgetfulness is losing our object of focus so that it will wander to that disturbing object. Forgetfulness serves as the basis for mental wandering (rnam-par g.yeng-ba).
