Samapatti and Progressive States of Absorption

Patanjali describes samadhi as the goal of yoga practice—a state of undistracted meditative absorption where the mind merges with its object. Abhidharma extends this with the doctrine of samapatti (attainments), mapping eight successive states of meditative absorption (jhanas) that can be systematically cultivated and verified through direct experience. The first four samapattis involve form-realm meditative states characterized by progressively refined mental factors: initial and sustained attention giving way to joy and equanimity, finally to singular-pointed peace. The next four involve the formless realms, where consciousness itself becomes the object of focus, leading to progressively subtle states until reaching the threshold of neither-perception-nor-non-perception. Abhidharma's genius lies in treating these not as mystical experiences but as verifiable states with specific cetasikas and jhanic factors. Patanjali's yoga practices (pranayama, pratyahara, dharana) become precise technologies for accessing these states, while Abhidharma's map ensures practitioners understand exactly what they're cultivating and why. This fusion transforms meditation from vague 'concentration practice' into a science of consciousness with clear milestones and measurable development.
