I am not sure this generally becomes a of the Easter message, but it is an integral part of the resurrection.
"easter" has zero to do with the resurrection of the Lord Jesus Christ.
Pagan origins of easter
the Easter story comes from the Sumerian legend of Damuzi (Tammuz) and his wife Inanna (Ishtar), an epic myth called “The Descent of Inanna” found inscribed on cuneiform clay tablets dating back to 2100 BC. When Tammuz dies, Ishtar is grief–stricken and follows him to the underworld. In the underworld, she enters through seven gates, and her worldly attire is removed. "Naked and bowed low" she is judged, killed, and then hung on display. In her absence, the earth loses its fertility, crops cease to grow and animals stop reproducing. Unless something is done, all life on earth will end.
After Inanna has been missing for three days her assistant goes to other gods for help. Finally one of them Enki, creates two creatures who carry the plant of life and water of life down to the Underworld, sprinkling them on Inanna and Damuzi, resurrecting them, and giving them the power to return to the earth as the light of the sun for six months. After the six months are up, Tammuz returns to the underworld of the dead, remaining there for another six months, and Ishtar pursues him, prompting the water god to rescue them both. Thus were the cycles of winter death and spring life.
The Sumerian goddess Inanna is known outside of Mesopotamia by her Babylonian name, "Ishtar". In ancient Canaan Ishtar is known as Astarte, and her counterparts in the Greek and Roman pantheons are known as Aphrodite and Venus.
the story of Inanna and Damuzi is just one of a number of accounts of dying and rising gods that represent the cycle of the seasons and the stars. For example, the resurrection of Egyptian Horus; the story of Mithras, who was worshipped at Springtime; and the tale of Dionysus, resurrected by his grandmother. Among these stories are prevailing themes of fertility, conception, renewal, descent into darkness, and the triumph of light over darkness or good over evil.
Easter as a Celebration of the Goddess of Spring
A related perspective is that, rather than being a representation of the story of Ishtar, Easter was originally a celebration of Eostre, goddess of Spring, otherwise known as Ostara, Austra, and Eastre. One of the most revered aspects of Ostara for both ancient and modern observers is a spirit of renewal.
Celebrated at Spring Equinox on March 21, Ostara marks the day when light is equal to darkness, and will continue to grow. As the bringer of light after a long dark winter, the goddess was often depicted with the hare, an animal that represents the arrival of spring as well as the fertility of the season.
