On the 21st of June, the day of summer solstice, spend time with the sun, go for a walk, collect flowers or other objects that speaks to you. When you find a spot which you feel attracted to it, create a geometric composition with what you found and offer an altar to the sun.
Set your intention for this altar.
Bring the fresh elements back home and put them in a bowl of water. Leave it for the whole day under the sun (if there is no sun, draw a hole in the sky with a pencil).
After sunset, when the moon appears in the sky, pour the water into a bottle. Keep this water for the whole year - this water will be a reminder to give you energy when you need.
