Certain activities can help a person gain presence.
These are not 'meditation'.
They are simply activities or exercises that encourage you to be conscious of the 'here and now'.
Ultimately, everything that you do should help to bring your mind back to reality; whether it is washing dishes, walking on the beach or sitting quietly.
The activity itself is not important - it simply serves to initiate the condition of presence.
If you come to rely upon the activity, this is a mistake.
