Do you see how excitable a dog becomes when it sees its prey?  Single-minded focus blocks out all else from
its awareness.  Can you be the
single-minded focus of love?  This is the
state you want to aim for in meditation to know your true self.  Whilst the mind wants to wander, pure
consciousness is stillness and focus. 
How to achieve this?  With
intention, desire, and devotion.  The
more you sit in this state of pure focus, the more you come to know your true state
of utter peace and tranquility.  There is
no need to stay there long in this fully focused state—merely to experience it
on a regular basis so that when things become hectic around you, you can return
to this sacred place and state at will.
