To me courage is the ability to live. Courage is the ability to be quite ordinary and yet be content, and not see life as a huge burden. Ambition or what we call drive is often driven by innate anger, which can turn completely negative.
But beyond all that true courage is the ability to be comfortable with the unknown and welcome it as the natural order of the universe. It is not just the acceptance of death, but also the acceptance of control as the great illusion. True courage is the ability live in the moment fearlessly and with immense love with no opposing force.
On passion, desire and attachment
Passion belongs to the moment and Attachment is addicted to the past or the future. Attachment is desire while Passion is pure acceptance. Desire brings with it the fear of non achievement, but Passion has no fear. Mira's passion for Krishna was not a desire for Krishna but a Pure Passion. It was not an attachment to Krishna but a love so pure and passionate that she was one with Krishna. Passion is universal and flows consistently and is limitless, the bhakti of Mira was never ending in it's force of expression.
Shakespeare wrote a great line for Juliet (Romeo and Juliet) " he is a beggar that can measure his worth". She was speaking about love. Passion is beyond measurement, it explodes through the clouds of contextualization. For it has no measure to compare it to.
Attachment and desire are contextualized and contained by measurement - they are reigned in by fear of non achievement - and by comparison, self loathing and envy. Passion is not only selfless but the letting go of the self. Passion is action not addicted to a defined result. Pure Passion leads to pure action. Attachment leads to reaction, not action".
