Definitions

The Abhidharma-samuccaya states:

What is lack of trust (ashraddhya)? It is the mind associated With the category bewilderment erring (moha) which does not have deep conviction, has lack of trust, and has no desire for things positive. It provides the basis for laziness (kausidya).

Mipham Rinpoche states:

Lack of faith (ashraddhya) belongs to the category of delusion (moha). It is to not be interested in what is true and virtuous. It forms the support for laziness (kausidya).

Alexander Berzin explains:

Disbelieving a fact (ashraddhya; Tibetan: ma-dad-pa) is a part of naivety (moha) and has three forms that are the contrary of the three forms of believing a fact to be true.

• Disbelieving a fact that is based on reason, such as disbelieving behavioral cause and effect.
• Disbelieving a fact, such as the good qualities of the Three Jewels of Refuge, such that it causes our mind to become muddied with disturbing emotions and attitudes and to become unhappy.
• Disbelieving a fact, such as the existence of the possibility for us to attain liberation, such that we have no interest in it and no aspiration to attain it.
