Sutra 1.17

At the Whetstone Park of Roses

वितर्कविचारानन्दास्मितारूपानुगमात् संप्रज्ञातः॥१७॥
vitarka vichaara ananda asmitaa rupa anugamaat sampraj-jaata-ha ॥17॥

Swami Sivananda: ‘Samprajnata Samadhi or concrete meditation is that which is accompanied by argumentation, deliberation, happiness, egoism and form.’ This means that the end result of the meditation or the union of self and Self is not formless/abstract but is concrete.

Based on committed practice and non-attachment, the practitioner or meditator moves through the four stages to a state of objectless concentration. Patanjali explains each stage in turn.
