We all have symbols. Symbols are quite universal, not because of any
universal soul or anything like that, but because we form the symbols
The dove is not a symbol of peace because the dove would be somehow a
peaceful bird, but because everytime we see or hear something about
the peace, we also see the white birds.
And in the school, when one should draw something for Mother's Day or
Independence Day, the same symbols are everywhere.
Now, we can - and should - form our own book of symbolism. (Yes, write
them down. You might want to write down your own experience too - like
your dreams and what usually follows some certain dream symbols, and
stuff like that.)
The unconscious is very obediant and will comply to anything you tell it.
So just go on and choose the symbolism you want.
If you want the horse stand for freedom, that's what it will stand for.
If you want the snakes to stand for wisdom and advice, that is what
they will stand for.
And if you want to make it easier for yourself, just use the symbols
there already are.
To make it easier for your unconsciousness, meditate over the
symbolism, repeat the symbolism to yourself.
But do remember to write it down. It is possible, that you have
forgotten, what a symbol means to you, when you need it.
