An intellect governed by the mode of passion lacks discernment and clarity in distinguishing between righteousness (Dharma) and unrighteousness (Adharma), between what should be done and what should not be done. Dharma refers to righteous conduct, actions aligned with moral principles and ethical values, while Adharma signifies unrighteousness, actions contrary to moral laws and spiritual principles. An intellect influenced by the mode of passion fails to discern the difference between these two, leading to confusion and moral ambiguity.

The verse underscores the significance of clarity and discernment in guiding one's actions. Without the ability to distinguish between right and wrong, individuals are prone to making decisions based on personal desires and impulses, rather than moral principles and ethical considerations.

Krishna addresses Arjuna, highlighting the consequences of an intellect governed by the mode of passion. Such an intellect lacks the capacity to understand things as they are (ayathāvat) and perceives reality through the lens of personal biases and desires, distorting one's judgment and discernment.

Furthermore, Krishna's teachings in this verse caution against the detrimental effects of passion-driven decision-making. Actions motivated by passion often lead to conflict, confusion, and moral degradation, hindering spiritual growth and evolution.

This verse serves as a reminder of the importance of cultivating wisdom and discernment in life. By developing clarity of thought and aligning one's actions with moral principles and ethical values, individuals can transcend the influence of passion and attain spiritual liberation.

In essence, this verse from the Bhagavad Gita underscores the significance of discernment and moral clarity in guiding one's actions. It encourages seekers to cultivate wisdom and discernment, enabling them to distinguish between righteousness and unrighteousness, and to lead a life guided by moral integrity and spiritual principles. Through the cultivation of discerning intellect, individuals can transcend the limitations of passion and ignorance, and attain spiritual enlightenment and inner peace.
