The Buddha's way points to three possible doors to liberation: dukkha (suffering), anica (impermanence), and anatta (not self). For each of us, the door may be different. For me, dukkha has been, is the gateway. Whenever I pay close attention, I always find suffering, even during the happiest moments. And it is the willingness and conviction of the worthiness to fully explore such suffering that always lead me to break free. This is in marked contrast to times past when I used to dread 'my' suffering.
From Ajahn Sumedho, in The Four Noble Truths:
With mindfulness, we are willing to bear with the whole of life; with the excitement and the boredom, the hope and the despair, the pleasure and the pain, the fascination and the weariness, the beginning and the ending, the birth and the death. We are willing to accept the whole of it in the mind rather than absorb into just the pleasant and suppress the unpleasant. The process of insight is the going to dukkha, looking at dukkha, admitting dukkha, recognizing dukkha in all its forms. Then you are no longer just reacting in the habitual way of indulgence or suppression. And because of that, you can bear with suffering more, you can be more patient with it.
No longer being deluded about the nature of life. Not hoping for a life without suffering. And paradoxically finding moments of freedom, with no self-created suffering.
Does dukkha 'speaks' to you? How are you with it?
