In English
You want to eat food and fruit which is very good and tasty, but in order to get such fruit, you cannot use seeds which will give poisonous plants. The kind of fruits that you get on a tree that you plant will depend on the kind of seeds that you put in. If you put in seeds of poisonous plants and expect tasty fruits, how can you get them? The troubles that you have or the good that you have now will depend upon the kind of actions you have done in your previous birth. Not to recognise this and blame others is not correct.
