Swadharma is that action which is in accordance with your nature. It is acting in accordance with your skills and talents, your own nature (svabhava), and that which you are responsible for karma.
Any action that does not make you feel afraid or restless is swadharma. That action which you feel compelled to do, without which you feel restless is swadharma. Now do not misunderstand this and say, ‘I feel restless if I do not drink alcohol’. No! Not at all.
Every time you feel restless, it not always because of Swadharma. But at the same time not following your swadharma always makes you feel restless.
That is why it is said in the Bhagvad Gita, ‘ (3.35).
When we do something without authenticity, just to show off to another person, that is when we feel fear because such action is not genuine, it does not come from the heart. But when we do something that is authentic and from the heart, then there is no fear.
When someone speaks lies, they definitely feel scared somewhere inside. But someone who speaks the truth does not feel scared at all. In fact speaking the truth and abiding by it brings so much strength to you, isn’t it? This is what swadharma is.
When we follow that which comes naturally to us in our life, then it brings abundance and prosperity to us. When we flow in accordance with our nature, we grow from within. Any action that uplifts us is our swadharma.
