I’m gonna start with what it is officially said to glean and being a gleaner: Gleaners were traditionally allowed during daylight hours, to go into a field where it’s been harvested and find what is left to gather for their needs and that is what it is to glean.
∴ Gleaning in each moment, is an art of meeting needs when all else seems taken. Ponder on that, to have your needs for say peace, joyful fun, laughter, within each moment to cover over a stressful situation. So you’d have to seek something within the moment that is still there and is peaceful, joyful and makes you laugh. Yep, it’s an art alright and well worth the practice, but that in 1857 in England gathering in arms of food from the edges of the harvested field, yes, for some it was probably out of necessity (isn’t it always). My advice: Always be a gleaner.
