Since they are attached to the ground, plants are obliged to put up with heat, cold, wind and storms

"Since they are attached to the ground, plants are obliged to put
up with heat, cold, wind and storms. These are certainly
difficult conditions, but they grow and produce flowers all the
same. And their colours are so beautiful and their fragrance so
pleasant!
People on a spiritual path are, symbolically, exposed to the
same difficult conditions as plants. And yet these conditions are
far preferable to those chosen by lazy people, who stay safely in
their 'lofts'. Of course, in a loft seeds won't be exposed to bad
weather, but they run other much worse risks: they might go
mouldy, be eaten up by mice or maggots or, worst of all, not be
put to good use. And being useless is the worst fate there is.
Once planted in the spiritual life, humans meet with obstacles,
but at least they are on the right path: they grow, they stand up
for themselves and they create."
