What’s the difference? The net result is the same, an action or experience is not repeated.
I’ve been thinking a lot about this recently and believe it comes down to time frame and perspective. Never again is usually an action of avoidance, the result of an unpleasant experience. The last time could be the result of natural aging (the last time you rode in a pram), a change in personal preferences, things wearing out, moving to a new home or city, or you decide to focus on something new.
When will that last time come and can you experience it with joy and gratitude instead of sadness for the loss?
Forty one years ago I'd reached a level of independence after leaving my parents home and city of birth to begin my second year at university. The degrees of freedom were almost boundless and despite the responsibility of studying for my Zoology major there was plenty of opportunity to satisfy my boundless youthful curiosity.
This included my first foray into meditation and began with an introductory Transcendental Meditation course that lasted several months. During particularly stressful times, despite years without any meditation, I found that returning to my TM practice, even for brief periods, helped restore some balance.
Despite this periodic relief I never fully understood how or why it might be good for me.
