I’m drifting in here a bit late…
And I’d like to add the perspective of a gardener with a love of mathematics. Presenting this clearly and concisely is a bit of a struggle, so I beg patience in reading.
The present focus on “rationality” as a translation does not sit well with me. Rationality is simply a lever, and like any lever can be used skillfully or not. A lever can lift a load to benefit. It can also be a truncheon to oppress others into submission. Rationality is just a lever.
Rationality is also incomplete. The rigorous decomposition of arguments into axioms and logical derivations is incomplete. It also does not match the common experience of struggling with a vexing problem only to wake up in the clarity of morning to a solution derived through no rational experience.
And where does gardening fit in here? Well, as a rational person, I determinedly set about gardening with a rational mindset. And after years of effort I found the rational approach limited and incomplete, even to the point of actually being harmful. So I abandoned my electronics. I abandoned my software programs. I abandoned my fancy hydroponic chemicals. And I tried something different.
What I tried was gardening with an open heart.
And the garden breathed a sigh of relief. Insects returned. Birds showed up. The power failed and the plants laughed with joy. It has been quite remarkable. When I opened my heart to the garden, the earth responded in kind. When I fed the earth, it opened its arms and fed me in return.
So for me, the “yoniso manasi kaara” is just “well grounded with an open heart”. That’s a lot of words and I am not a wordsmith, but simply waving hands in a different direction.
