Do the horns matter at all?
It’s perhaps the thorns inside that are more relevant, than the horns outside.
As Krishna explains in chapter 16 of the Gita, an asura would be a person who does not live by dharma. And that an asura’s sole aim in life is to enjoy sense pleasures. That’s it, as simple as that!
We each perhaps intuitively feel and believe that we live by dharma. But do we really? Are there never any transgressions?
The reality is that we each have a mix of daivic and asuric qualities, a bit of good and a bit of bad. The effort has to be, constantly, to introspect, and force out the bad, while growing the good.
