No wonder the main motif on this card bears a clear resemblance on the Holy Grail.  This card has a very spiritual and emotional context. It often  suggests a beginning of a new relationship. What is important is to understand that this card is the seed and the essence of the Cups suit. It suggests a  beggining of a new emotion, peace, romantic relationship or just friendship. It often stands for start of harmonious family life. As a member of the Cups family it also has a say about creativity, imagination, faith and deeper levels of consciousness. It is also important to see that this seed is not always too visible to us. We may have a seed of the new relationship in our heart before our mind can see that. Sometimes it just shows that the essence of some life problem is in some kind of emotional, "watery" issue.  Five streams pouring out of the cup probably stand for five basic senses through wich we experience the world. Once again we see the Hebrew letter Yod raining from above, clearly a sign of the divine grace, a help from above; thus, following your intuition is an important part of message of this card. The cup is suspended in the air above some vaste body of water, emphasizing its connection with the water element, waterflowers symbolize the creative power of imagination.

Positive: beginning of new relationship, intuition, abundance, joy, contentment, faithfulness, compassion, creativity, friendship, your time is coming soon, there is more work to be done but victory is yours. Seed of success.

Negative: dissolution of relationship, lost or unrequired love, despair, loss of faith, lack of empathy. Try to resolve issues from the past so everybody involved can move forward.

The waters are beneath, and thereon are water-lilies; the hand issues from the cloud, holding in its palm the cup, from which four streams are pouring; a dove, bearing in its bill a cross-marked Host, descends to place the Wafer in the Cup; the dew of water is falling on all sides. It is an intimation of that which may lie behind the Lesser Arcana. Divinatory Meanings: House of the true heart, joy, content, abode, nourishment, abundance, fertility; Holy Table, felicity hereof. Reversed: House of the false heart, mutation, instability, revolution.
