Things in the memory is void, current things is exist, but we hardly feel that it is exist. Things in the future are not exist, but it is we expect to exist.

Therefore, we lived in three states.

First, we recollected things that happened yesterday, Last week, last month, last year or preexistence.  An old man often lives in memory. A broken-hearted person always lives in memory making him sorrow.

Second, we live in current. When one has breakfast and praises meals, he lives in current. This time our conscious focus on current things into view. Children always live in current because they don’t have things needed to memory. They are easy to happy and unhappy depending on what appear.

Third, we live in the future. We often expect something we want to have so in some extent we live in the things we expected. More we want to have it, more we live in it.
