From Wiki ( horrible source but a beginning point always )
?tusa?hara often written Ritusamhara,[1][2] (Devanagari: ????????; ??? ?tu, "season"; ????? sa?hara, "compilation") is a long poem or mini-epic in Sanskrit by Kalidasa. The poem has six cantos for the six Indian seasons - gri?ma (summer), var?a (monsoon/rains), sarat (autumn), hemanta (cool), sisira (winter), and vasanta (spring). It is generally considered to be Kaldiasa's earliest work.
The word sa?hara is used here in the sense of "coming together" or "group".[3] It is often translated as Medley of Seasons or Garland of Seasons, but also mistranslated as "birth and death" of seasons, which arises from the alternate meaning of samhara as destruction.
The changing seasons are depicted against the thematic backdrop of how lovers react to the landscape. This imbues the poem with a strong strand of erotic love (shringara) rasa.
Ritusamhaaram... or Ritusamharam 0r Ritusamhara as in a misspelt Itrans, but it is The Medley of Seasons or The Garland of Seasons. around the deity of Nature called year. It is not annihilation of seasons according to the wording - samhaara- but, if a long vowel A is substituted in the word samAhAra, then it is an assimilation of seasons Ritu - samAhAram. These six seasons are the makeup material for the presiding deity of Nature, namely shiva-pArvati , the Five-faced God shiva, whose five faces symbolize the five subtle elements of creation.
Now it makes a somewhat sense... CV doing poetic justice to the DKDM đ. However, it is said that, Prakriti did ask Shiva to sanctify her by touching her in each season. Shiva told her it is not needed, but she insisted that it is not for her that sanctification is needed it for people. Shiva gladly agreed.
I think I made some sense.. If not I will try explain again..
