“Laka’s themes are tradition, heritage, weather and arts. Her symbols are lei flowers, dance and the color yellow.
Laka is the Hawaiian Goddess of Hula, through which the myths, legends and histories of the Hawaiian people are kept intact. Today She charges us with the sacred duty of collecting the treasures of our personal legacies and recording them for sharing with future generations.
In stories, Laka is the sister of Pele (the volcano Goddess) and a nature Goddess who can be invoked for rain. Artistic renditions show Her wearing yellow garments, bedecked with flowers and always dancing.
The cherry blossoms of the Cherry Blossom Festival in Hawaii are spiritual, not real, symbolizing the power of tradition among the predominantly Japanese community. On this day people gather together and honor their heritage by participating in martial arts, Japanese dances, weaving and arts competitions. So, if there’s any art or craft you learned from an elder in your family, take the time to display that craft or work on it today to commemorate Laka’s attributes.
If possible, get together with members of your family and begin creating a family journal that will record all the important events in your lives. Cover the journal with yellow paper dabbed with fragrant oil to invoke tending care on the sacred documents.”
(Patricia Telesco, “365 Goddess: a daily guide to the magic and inspiration of the goddess”.)
“Laka is most well known as the Goddess of the hula and the forest. Even today, in very traditional hula halaus, an altar or offering is prepared in honor of Laka with a very specific succession of plants.”  After the dance, “the altar is dismantled and ever leaf is taken to the ocean or a deep stream as a way to honor Laka further.
She is also known as the Goddess of the wild woods and over all vegetation. Plants sacred to Her are: maile, Lama, hala pepe,`ie `ie, ki, `ôhia lehua, and palai. The maile flowers are commonly used to make Lei, which are draped over the neck. As vegetation Goddess, She is associated with the nourishing elements of light and rain. Rain connects Laka to Her husband, Lono, the fertility god who descended to earth on a Rainbow to marry Her.” 
“In some traditions of Hawaii the hula was brought to the islands by a brother and sister, both named Laka. Although prayers are addressed to Laka in many hula performances, few, if any, hulas are ever dedicated to her. Because of many stories connecting Laka to impregnation and fruitfulness, Beckwith calls Her ‘the Goddess of love.’ The name laka means “gentle, docile, attracted to, to attract,” and there are old chants asking Laka to attract not only love, but wealth. Of very different origin, She was nevertheless incorporated into the Pele religion. Due to Her associations with the forest She represents the element of plants.”
