In order to have the attainment of Buddhahood one must practice developing the first stage and only then should go on to practice completion stage. Through practising ‘developing stage’ only, one may necessarily acquire the five fold miraculous power, yet, the practice of the ‘developing stage’ is the integral part of the path for attaining the highest goal i.e. Buddhahood. Generally ‘developing stage’ is the visualization of the meditational deity and his circle of mandala visualized clearly and simultaneously in all details. Here the artists must be careful in creating the images of various deities with due attention, following the cannonical texts or the instructions of a qualified tantric Buddhist master.
In profound ‘completion stage’ is the practice of meditation on emptiness on the nature of these deities. So proper care must be taken into consideration to produce images of a genuine nature so that it becomes the object of faith and devotion.
