James Allen says:

A man's mind may be likened to a garden which may be intelligently cultivated or allowed to run wild, but whether cultivated or neglected it must and will bring forth.  If no useful seeds are planted, then an abundance of useless weed seeds will fall therein and will continue to produce their kind.


If we plan a garden in our minds eye we see the fully grown garden with big shady trees, flowerbeds full of colour, green lawns, colourful rockeries.  But we only get that with a lot of hard work, clearing, feeding, planting and tending the garden.


So if our minds are like a garden they also need some good hard work.  We need to dig deep and get rid of all unwanted thoughts and rubbish that have probably been around for years.  And then the exciting part begins when we plant good seeds, which are strong pure and positive thoughts.


But we need to remember that that isn't enough.  We've got to tend the garden or it'll soon go to seed and be full of weeds, aphids etc.  If we neglect our minds impure or negative thoughts soon slip in and swamp all that is good.  Cultivating a good garden needs constant work, so too with the mind.  We have to be aware of and control it constantly.
