"Vajrayana reveals an infinite hall of mirrors in which there is no final answer beyond the fleeting answers shifting endlessly within the empty mirror. Answers can only be understood by allowing emptiness. To allow emptiness requires that we relinquish the need to concretise an answer. Answers are the impermanent manifestation of a permanent emptiness."
