Generic Transformation Spell from the Element Encyclopedia of 5000 Spells:
Hold an apple in your hand.
Consider what you want to be - or who you truly are
Take as long as you need but don't put that apple down
When your ready, line up a mirror, a yellow candle and the apple
Gaze into the mirror while the candle burns
After the candle has burnt out, consider whether you still desire this transformation
If so, eat the apple.
Associates with transformation are frankincense incense (associated with phoenix), essential oil of helichrysum (powerful for assisting the process of emotional transformation), and the Tower tarot card. Also think of sympathetic magick - images of eg caterpillars/butterfly's and phoenix's and see if you can work something around them, such as a guided meditation.
Hope this helps!
