The rose is the flower of love and surrender.
Experience shows that not only can surrender come by love, but love also can come by surrender or grow with it from an imperfect to a perfect love. One starts by an intense idea and will to know or reach the Divine and surrenders more and more one's ordinary personal ideas, desires, attachments, urges to action or habits of action so that the Divine may take up everything. Surrender means that, to give up our little mind and its mental ideas and preferences into a divine Light and a greater Knowledge, our petty personal troubled blind stumbling will into a great, calm, tranquil, luminous, Will and Force, our little, restless, tormented feelings into a wide intense divine Love and Ananda, our small suffering personality into the one Person of which it is an obscure outcome. If one insists on one's own ideas and reasonings, the greater Light and Knowledge cannot come or else is marred and obstructed in the coming at every step by a lower interference; if one insists on one's desires and fancies, this great luminous Will and Force cannot act in its own true power — for you ask it to be the servant of your desires; if one refuses to give up one's petty ways of feeling, eternal Love and supreme Ananda cannot descend or are mixed and split from the effervescing crude emotional vessel.
