What is the Third Noble Truth?
The Third Noble Truth is that suffering can be overcome and happiness attained. This is perhaps the most important of the Four Noble Truths because in it the Buddha reassures us that true happiness and contentment are possible. When we give up useless craving and learn to live each day at a time, enjoying without restlessly wanting the experiences that life offers us, patiently enduring the problems that life involves, without fear, hatred and anger, then we become happy and free. Then, and then only, do we begin to live fully. Because we are no longer obsessed with satisfying our own selfish wants, we find that we have so much time to help others fulfil their needs. This state is called Nirvana. We are free from psychological suffering.
Actually I really appreciate the above definition, even if I feel it is a bit happy happy joy joy sounding.
But I would like to share my heretical view.
The third noble delusion is that there is suffering to be overcome.
In each moment we are naturally happy and free. We are already living fully without conditions.
To really go to the moment is almost like a dream. But it is the opposite of a dream. This is the state of Nirvana; where we are free from suffering. Unfortunately, we are conditioned against this state; the good news is you can transcend this conditioning.
Be well and happy,
