The administrative acumen of His Grace is far beyond what words can express. He is a spiritual leader, dynamic enabler, prolific orator, voracious reader, pungent writer, tactful negotiator, valiant defender of the law, compassionate at heart and a wonderful team man. He respects diversity of opinion, but would not easily budge or compromise ethical principles. He retains his lovable ness, humility and simplicity. He is a person with golden tongue, acceptable to all people irrespective of cast, colour or religious commitments.
