The Veil is Thin
Even though it is a red, seemingly fiery painting, it belonged in the Water suit in Lane's Greenwitch Tarot because it involves intuition and psychic knowing, specifically connecting with spirits (not all human) who have passed into other realms. All watery things.
Thus it is the Ancestor of Water:
Spirits and ancestors on the other side of the veil – our beloved dead – can still be present to us, giving guidance and messages about matters both mundane and cosmic. Some see, hear or feel them easily. Especially at Halloween/Samhain when the veil between the worlds is thin. Others of us - like me - have to slowly learn to trust the often subtle whispers that come from these realms. It’s not unusual for people to see long gone loved ones at the moment of their own death. A ladder is a common symbol in many cultures of shamanically climbing to be with the spirits. “We are climbing Jacob’s ladder…”
Do you receive messages from the other side? Are they to be delivered to others? Learn to trust subtle knowings and random thoughts of someone crossed over that come into your mind. You are being called to hone and use these skills. Datura Essence (Angel's Trumpet) can help at the gateway both for communication and the passage over.
