Usually we find it difficult to control our mind
It seems as if our mind is like a balloon in the wind – blown here and there by external circumstances. If things go well, our mind is happy, but if they go badly, it immediately becomes unhappy. For example, if we get what we want, such as a new possession or a new partner, we become excited and cling to them tightly.
However, since we cannot have everything we want, and since we will inevitably be separated from the friends and possessions we currently enjoy, this mental stickiness, or attachment, serves only to cause us pain. On the other hand, if we do not get what we want, or if we lose something that we like, we become despondent or irritated.
