Akushala means inauspicious in Hinduism. The tenth verse in chapter eighteen of the Bhagavad Gita says – An intelligent person is one who has renounced the fruit of all actions and whose doubts have been dispelled, who is good in nature, has neither aversion for inauspicious actions nor does he have attachment for auspicious ones.
The Bhagavad Gita says that a wise person neither expresses his hatred of evil nor attachment to anything good. The ideas is significant when we note here that reactions to pleasure or pain, gain or loss, and other duals pertain to the mind and they are caused when the mind is extrovert. An extrovert mind is polluted due to the external objects perceived through sense organs. Thus feeling either good or bad causes deflection of the mind and creates modulations. Elimination of the modulations is the objective of the mind, so that it can regain its calm, serene, and peaceful natural state.
Primarily, the mind is pure and untainted, but due to association with the sense organs it loses its original state and becomes contaminated. Yoga is the perfect ideal and helps prevent contamination and enables the mind to regain the state of serenity. Patanjali has declared both attachment and aversion as pain-giving (Patanjali’s Yoga Sutra II: 3). The Bhagavad Gita (VI: 26) ordains that one should not think of anything. The steady and non flickering state of mind is compared to a lamp in a windless place (Bhagavad Gita VII: 19). Therefore, an intelligent person should not think either favorably or adversely about either auspicious or inauspicious actions.
