In fact, during Victorian times, there was a fully developed ‘language of flowers’ which was used to convey secret messages. Also, as we know, in the Vedic tradition, specific flowers are offered to a particular deity or during a specific prayer offering.
So, basically there have always been specific meanings associated with the Flowers.
You could ask a question and then see which flower comes to you in your mind’s eye as an answer for your question.
The other option is to write a name of a flower on an index card and then shuffle these bunch of cards. You could then ask a question and then pick out a card which ‘feels’ right for you.
Then you can look up the meaning associated with the flower you received as bearing the answer to your question.
