यहाँ दीनता का क्या अर्थ है और किस प्रकार वह विरोधी भाव है?
Here it refers to the feeling of being miserable i.e. being wretchedly unhappy or uncomfortable.
This is a virodhi bhaav because misery or being in a state of misery arises on account of one’s own lack of understanding of the soul.
Pride arises when one mistakes material gains as ones own permanent gains and views others who have less material gains lowly than himself/herself.
Misery arises when one feels dejected on lack of ones own material gains and feels as if he is lowly or less respectable than others around him. For example, A person having a cycle feeling sad when he sees that all of his other friends own a bike.
Mardav dharm advises the soul to realize that the soul should neither be haughty nor should be miserable since both are not the qualities of the soul.
The soul remains the same even when it owns huge temporary material gains or 0 temporary material possessions.
Therefore, being proud or miserable is not in tune with mardav dharma.
