Zen has nothing to teach us in the way of intellectual analysis; nor has it any set doctrines which are imposed on its followers for acceptance.
D.T. SuzukiDhyana is retaining one's tranquil state of mind in any circumstance, unfavorable as well as favorable, and not being disturbed or frustrated even when adverse conditions present themselves one after another.
D.T. SuzukiThe more you suffer the deeper grows your character, and with the deepening of your character you read the more penetratingly into the secrets of life. All great artists, all great religious leaders, and all great social reformers have come out of the intensest struggles which they fought bravely, quite frequently in tears and with bleeding hearts
