So says the last line of the "10 Phrase Life Prolonging Kannon Sutra":
延 命 十 句 觀 音 經 (Emmei Jukku Kannon Gyo)
KANZEON NAMU BUTSU
YO BUTSU U IN YO BUTSU U EN
BU PO SO EN JO RAKU GA JO
CHO NEN KANZEON BO NEN KANZEON
NEN NEN JU SHIN KI NEN NEN FU RI SHIN
Where is your attention? That is where your mind and heart are: that's what you're caring about at the moment.
And one of the points of that sutra, by the way, is to heighten one's degree of attention.
Geez, I could almost have Tweeted that.
