This quote means that what you get in life is like the seeds you plant in a garden. If you plant good seeds and take care of them, you'll get good fruits or flowers. But if you plant bad seeds or don't take care of them, you won't get good results. It's like saying if you do good things, good things will come back to you, but if you do bad things, bad things will come your way.
In simple words, it's like karma. If you are kind and helpful to others, they will be kind to you in return. But if you are mean and hurtful, you'll get the same treatment. So, it's a reminder to be good and do good because that's what you will receive in the end.
In life, the quote teaches us that our actions have consequences. If we work hard and make good choices, we'll have a better life. But if we are lazy or make bad choices, we'll face problems. So, it's a simple way to say that what we get in life is a result of what we do.
