One problem I have had is thinking 'about' jhana, and wanting to 'attain' it. From what I hear, it's beyond the level of ordinary thinking, and what's more, can't be owned any more than any other impermanent thing can...so I'm trying to let go of being too attached to the 'when' (when will it be attained? -
) and am just trying to focus my mind on cultivating the conditions conducive to it's arising.
And there's plenty of work to do there; abandoning watching any TV at all would help, for example! From what I hear, how we spend the hours off
the meditation cushion matters alot, not just one or two concerted efforts on
the meditation cushion.
I like Ajahm Brahm's analogy of 'building the house of peace', brick by brick; patience is vital. I'm trying to conceive of each meditation
as another 'brick', not as this big thing that 'might' happen - pah! Wondering 'when' I will attain jhana has gotten me absolutely nowhere. Letting go,
by way of contrast, at least leads to a degree of mental calm; and no matter how humble, it's better than mental agitation.
Just my two cents worth...
