Nikolai relays a story about a monk called Uvshin Khartskh. One day the monk asks the builders, who were working on a wooden house, about what the wood is made of? Seeing that nobody can answer his question, the lama explains that the wood consists of ‘very fine particles’. When the builders ask how small these particles are, the lama says that even if a single hair is divided into 360 parts, the ‘particle’ is still finer.
