As it's my birthday today, it seems appropriate to post something fittingly 'uplifting' and pertinent to the occasion. Hence, the five subjects for frequent recollection:
I am of the nature to age; I am not beyond aging.
I am of the nature to sicken; I am not beyond sickness.
I am of the nature to die; I am not beyond dying.
All that is mine, beloved and pleasing, will become otherwise, will become separated from me.
I am the owner of my actions, heir to my actions, born of my actions, related to my actions, abide supported by my actions. Whatever actions I shall do, for good or for ill, of those I will be the heir.
