Cramming your head full of knowledge or thinking as quickly as possible (i.e., becoming as robotically intelligent as possible), is not the same as mental development (e.g., practicing self-control, concentration, mindfulness/awareness, virtuous thoughts, etc.). Meditation (in Buddhism) means working to stop or to control thoughts and feelings, to become a better person.
Neuroscience’s steady movement towards early Buddhist-like views is interesting to watch, though the argument for nihilism in this video still seems anecdotal and atheism-dogmatic to me:
Developing virtues/merits for selfish reasons (e.g., for the karmic, physical, or social benefits) still contains a degree of unvirtuousness (i.e., a delusion of self). In my opinion, the point of being virtuous (and of Buddhism in general) is to completely cleanse this samsaric mind-body complex of whatever is obstructing it from becoming nirvanic, not to seek a nice future/rebirth in samsara.
Heaven might be so luxurious and pleasurable that beings there never think about nirvana or about making more merit, and, according to the seed-and-fruit concept from early Buddhism (i.e., that one instance of karma causes/conditions only one outcome), once the merit that is supporting a heavenly life runs out, one’s next rebirth may not be heavenly.
Pursuing either positivity (enjoyment, pleasure, luxury, etc.) or negativity (anger, punishment, vengeance, etc.) causes struggle and stress. Both are very unstable. Neutrality (contentment, balance, selflessness, etc.) seems to be the least stressful, most stable path.
If Buddhist bhikkhu(ni)s are dependent on lay people, how much would they be willing (or need) to change Buddhism to suit the popular views and desires of lay people, in order for the Sangha to survive?
Is this how things like protective chants/icons, Buddha as God, softening or ignoring the Vinaya rules, the Advaita Vedanta-type views in Mahayana, the many nation and ethnicity specific versions of Buddhism, etc. have worked their way into Buddhist traditions over the millenia?
Buddha images and statues might be the best representation of the early Buddhist notion of nirvana that is possible in this world, namely: existence without causality, where one thing doesn’t become another, nothing changes, “inflows” (physical or sensory input) don’t result in “outflows” (thoughts, words, or deeds) — like eternal statues with minds.
“The present moment is not an absolute. It’s something that you’re [unconsciously] fabricating, and the goal of the practice is to learn how to fabricate it in a new [nirvanic] direction…. The present is here to be used, and the teachings are here to teach us how to use it wisely” (Thanissaro Bhikkhu, “The Use of the Present,” 2016-11-28).
