‘Dhyana then is a discipline in tranquillization. It aims at giving to a mind the time for deliberation and saving it from running wild; it directs the vain and vulgar to the path of earnestness and reality; it makes us feel interest in higher things which are above the senses; it discovers the presence in us of a spiritual faculty which bridges the chasm between the finite and the infinite; and it finally delivers us from the bondage and torture of ignorance, safely leading us to the other side of Nirvana.’ (Sermons of a Buddhist Abbot)
