There are several stories about hOli. It is said that since hOlika, the sister of hiraNyakaSipu was immune to fire, he ordered prahlAda to be burnt along with her on a pyre. But he didn't die, she did. Then there is the legend of kRshNA and his rAsakrIDa (garba like dancing). The third one is the burning of kAma, the god of love by Siva. Even though he was burnt and cannot be seen, he is still visible to his wife ratI. The god kAma is known as manasija as he is born in one's mind. According to legend, he has five arrows of flowers -
aravindA (lotus) aimed at the chest causing craziness, aSOka aimed at the lips causing excitement, chUtaM (mango) aimed at the head causing loss of senses, nava mallika (jasmine) aimed at the eyes causing redness and neelOtpala (blue lily) when aimed causes death (metaphoric, not physical :-). In fact, hOli is really Valentine's Day in the Hindu calendar. Last year I took the rAsa theme for the hOli. This year, I have taken all the above five flowers and the bees (they are the string for his bow) and of course the hearts. They may not be all to the proper scale. Still, enjoy and comment!
