Suffering usually relates to wanting things to be different from the way they are.
Patience is supported & nurtured by a quality of forgiveness.
We need never be bound by the limitations of our previous or current thinking, nor are we ever locked into being the person we used to be, or think we are.
That's why it's called a practice. We have to practice a practice if it is to be of value.
True patience is grounded in wisdom and compassion.
Observing your thoughts, feelings & sensations is the grist of the practice.
