The Spiritual Master must be bona fide representative of Krishna, by disciplic succession, receiving orders from the superior, and the disciple must agree to abide by the orders of the Spiritual Master. This is the simple method of spiritual advancement; if you remember this principle it will be very nice.
Your letter is very encouraging, and I think in future your enthusiasm and energy can very suitably be engaged in the transcendental loving service of Krishna. Everyone of us has got a certain amount of good energy derived from Krishna, and when that energy is employed under the expert direction of Spiritual Master, one's life becomes successful. That is the secret of Krishna Consciousness. The Spiritual Master must be bona fide representative of Krishna, by disciplic succession, receiving orders from the superior, and the disciple must agree to abide by the orders of the Spiritual Master. This is the simple method of spiritual advancement; if you remember this principle it will be very nice. If you can carve Radha Krishna Murti very nicely, it will be a great service to the society. There is a quality of wood, which is very hard and strong and black and heavy; in India we call it iron wood. I think it is called ebony here. If you can carve Krishna from this ebony wood, and Radharani from another wood, one which is very hard, and of golden color, and from this same golden wood, Lord Caitanya (all of Them 24" in height, and Radharani a little less) then you can begin this work immediately. I'm so glad to learn that you are eager to serve Krishna in every way possible. This mentality is very rare, and I guess that you must have been engaged in Krishna's service in your previous life. To begin eager to serve Krishna is the greatest achievement after many many duration of pious life. So I entrust you to begin this work immediately. And concentrate your energy making this art perfection. So far Radha Krishna Murtis are concerned, you have many pictures in San Francisco, and you can do accordingly, and so far Caitanya Mahaprabhu Murti is concerned, I am giving you a rough diagram herewith.
