“Goddess Lada” by Lady-Ghost
“Lada’s themes are spring, protection, overcoming, kinship, energy, and joy. Her symbols are birch and bells. Lada bursts forth from Her winter hiding place today in full Slavic costume and dances with joy, grateful for spring’s arrival. As Lada moves, Her skirts sweep away sickness and usher in the earth’s blossoming beauty. She bears a birch tree and flowers to honor the earth’s fertility and to begin planting anew.
Sechseläuten, a traditional Swiss spring holiday, is overflowing with Lada’s vibrancy and begins with the demolition of a snowman, symbolic of winter’s complete overthrow. If you don’t live in a region where there’s snow, take out an ice cube and put a flowering seed atop it. Let is melt, then plant the seed with ‘winter’s’ water to welcome Lada back to the earth.
Bells ring throughout this day in Switzerland to proclaim spring and ring out any remaining winter maladies and shadows. Adapt this by taking a handheld bell (you can get small ones at craft stores) and ringing it in every room of the house, intoning Lada’s revitalizing energy. Or, just ring your doorbell, open the door, and bring in some flowers as a way of offering Lada’s spirit hospitality.
Finally, wear something with a floral print today or enjoy a glass of birch beer. Better still, make a birch beer float so the ice cream (snow) melts amid Lada’s warmth, bringing that transformative power into you as you sip.”
(Patricia Telesco, “365 Goddess: a daily guide to the magic and inspiration of the goddess”.)
“Lada is the Slavic Goddess of spring, love, and beauty. She was worshipped throughout Russia, Poland, and other areas of Eastern Europe. She is usually depicted as a young woman with long blonde hair. She carries wild roses, and is also known as the ‘Lady of the Flowers’. As Goddess of spring, Lada is associated with love and fertility in both humans and animals. She is said to return from the underworld every year at the Vernal Equinox, bringing the spring with Her.” 
“The Slavic Goddess of love and beauty, who appears as Freya, Isis, or Aphrodite with other peoples. She is, of course, linked to the planetary power of Venus who is, besides love and beauty, associated with fertility. Lada is represented as a girl with long golden hair sometimes with a wreath of ears of grain braided into Her hair, which symbolizes Her function of fertility deity thus making Her an aspect of Mother of Wet Land. A symbol of Sun, a mark of lifegiving power was sometimes on her breasts. As a fertility Goddess, Lada has Her annual cycles, which can be shown by the belief that She resides in the dwelling place of the dead until the vernal equinox comes. This world of the dead is called Irij, and here, besides Lada, dwells Veles, the horned god of cattle. [Does this story ring a bell? A connection between Persephone/Kore in Greek mythology or Oniata in the Americas?]
At the moment when Lada is supposed to come out into the world and bring spring, Gerovit opens the door of Irij letting the fertility Goddess bless the earth. At the end of summer, Lada returns to Irij (there is a similar myth in German mythology in which Freya spends a part of the year underground among the elves, whereas Greek Persefona dwells in Hades during the winter period). Although Her reign begins on the 21st of March, Lada is primarily the Goddess of summer. She follows Vesna, the Slavic spring Goddess. However, both of these Goddesses are associated with fertility so sometimes it can sometimes be difficult to separate their functions. As we can see, Lada’s reign begins in spring, the proof of which is ladenj, another name for April, given after this Goddess. Apart from the Sun, Lada is also associated with rain and hot summer nights, the ideal time for paying respect to the love Goddess.
Lada’s animals are a cock, a deer, an ant and an eagle, whereas Her plants are a cherry, a dandelion, a linden and a peony. Besides Venus, Lada is connected with the constilation of Taurus, which Aleksandar Asov wrote about in The Slavic Astrology. Here, we can once again Her function of fertility Goddess, whose reign begins in spring, mix with the function of the Goddess Vesna. A myth says that Lada is married to Svarog who is only with Her help able to create the world. According to another one, She is a companion of Jarilo, thus associated with Aphrodite, whose lover is Ares. Rituals performed in Lada’s honor are most often linked with contracting marriages, or choosing a spouse. One of the known rites is ladarice, also performed under the name of kraljice in Serbia. Vuk Karadžić described the basic characteristics of this ritual. On Holy Trinity Day, a group of about ten young girls gathers, one of them is dressed like a queen, another one like a king, and another one like a color-bearer. The queen is sitting on a chair, while the other girls are dancing around Her, and the king and the color-bearer are dancing on their own. In this way the queens go from house to house looking for girls of marriageable age. Jumping over the fire is another characteristic of rituals performed in Lada’s honor. This custom existed in all parts of Europe and its purpose was to ensure fertility as well as to protect people and cattle from evil forces.”  This very similar to the customs of Beltane; celebrating the May Queen and jumping the balefire for purification purposes and to ensure fertility.
“Lady Galadriel” by Josephine Wall
“Lada’s name means peace, union, and harmony. Lada creates harmony within the household and in marriages; She blesses unions of love with peace and goodwill. In Russia, when a couple is happily married it is said that they ‘live in Lada.’ Rituals performed in Her honor are most often linked with contracting marriages and and choosing a spouse.”
