You must improve yourself in order to improve the quality of your seeds. ‘What seeds?’ you will ask.

Your thoughts and feelings. Each one of your thoughts, each one of your feelings is a seed that reflects your strengths and weaknesses, and you sow these seeds all around you wherever you go.
The ground on which all these seeds fall is found on the astral and mental planes, and one day when you visit these regions, and ask, ‘Where have all those thistles and thorns come from?’ you will be told that they are your crop, that you are the one who planted them.

‘And these roses and lilacs and lilies?’ Well, it will also be explained to you that they too are your work: the good thoughts and feelings you scattered around you.
