Dharma is derived from the Sanskrit root 'dhri', which means 'to uphold' or 'to sustain'. It refers to the cosmic order and the ethical duties of an individual.
In the Bhagavad Gita, the concept of Dharma is central, starting with the very first word 'Dharmakshetre'. Krishna urges Arjuna to follow his Swadharma (personal duty) as a warrior.
Practically, Dharma means doing the right thing in any given situation, even when it is difficult.
In modern times, Dharma can be understood as 'integrity'—aligning your actions with your highest values and professional responsibilities.
