You can leave it up to mother nature to program the crystal and you can affirm what you would like to manifest.
Otherwise, you can follow the below steps:
• Choose a crystal that resonates with your desired intention
• Get cozy with your crystal and find a nice state of mind for yourself
• Get calm and relaxed
• Visualise yourself living your intention
• Send feelings of gratitude to the universe
Go ahead and use your crystal as you desire!
Ensure you follow my steps on cleansing your crystal once you have finished using it.
