Natural leaf carving is actual manual cutting and removal of a leaf's surface to produce an art work on a leaf. The process of carving is performed by artists using tools to carefully remove the surface without cutting or removing the veins.
There is nothing to practice. To know yourself, be yourself. To be yourself, stop imagining yourself to be this or that. Just be. Let your true nature emerge. Don’t disturb your mind with seeking — Sri Nisargadatta Maharaj
