There is the earth and and there is heaven: they both seek our attention, and we must learn how to work for the one and for the other, first ensuring we make a clear distinction between earthly material values and spiritual values. For as long as we are on the earth, there is no question of abandoning it.
But we must place our feet only on the ground; and hold our head in heaven, that is to say, put wisdom and love into all our activities so that everything we do brings us closer the divine world.
To illustrate this, I would say that we must see our life on earth like that of plants.
Look at trees – they remain fixed to the ground, but thanks to the water and light they receive from above, they transform the earth and foster its evolution by bearing flowers and fruit. Trees show us how to work on the earth while also directing ourselves towards heaven.
And this is another lesson nature teaches us: not only must we not neglect the earth, matter, we must also try to transform it.
