Though it's role in the process of waking up is pivotal, intention is very subtle, rarely conscious, and outside the control of self. Purification is made possible through the appropriate use of mindfulness to the things we do and say.
In his teachings on dependent origination found in the Upanisa Sutta of the Samyutta Nikaya, the Buddha explained the path in such positive terms as joy, rapture, tranquillity, and happiness.
When we understand that our happiness and unhappiness depends on our actions, then we can act with intentions that are loving and generous. This is what brings about the happiness we long for.
