Has anybody had the experience of going through long periods (months) during which the practice gets less focused and the level of absorption diminishes, compared with previous times? I used to experience intense bliss in almost every session and have barely experienced any for the last 2-3 months, even though I continue to be diligent with daily practice. Has anybody else experienced similar fluctuations in sitting performance? Sometimes I worry that I have "screwed something up" about the method.
"I do not perceive even one other thing, o monks, that when developed and cultivated entails such great happiness as the mind" (AN 1.10, transl. Ven. Bhikkhu Bodhi)
"So this spiritual life, monks, does not have gain, honor, and renown for its benefit, or the attainment of moral discipline for its benefit, or the attainment of concentration for its benefit, or knowledge and vision for its benefit. But it is this unshakable liberation of mind that is the goal of this spiritual life, its heartwood, and its end," (MN 29, transl. Ven Bhikkhu Bodhi)
