  "so_what_questions": [
    "If ātma-viśuddhi (self-purification) is only preparatory for Advaita but is itself liberation for Viśiṣṭādvaita (bandha-vimukti), does this verse describe one stage or the final goal — and what changes in practice if it is the latter?",
    "Madhva's bhāṣya spans three verses in a single line while Madhusūdana devotes a long technical analysis to the same verse: what does that compression versus expansion reveal about each school's theory of the role of technique in spiritual life?",
    "Vallabha says the yogī is 'already mounting' (ārurukṣoḥ) when this verse applies — does that mean the āsana discipline of 6.11-12 is irrelevant to someone fully in Puṣṭi-mārga, or is it re-read as itself a gift of grace?",
    "Madhusūdana invokes the three bhūmis (grounds) of mental distraction and names the goal as samprajñāta-samādhi — a specifically Yoga-darśana category — inside a Vedānta commentary; how much of Patañjali's Yoga-Sūtra framework is silently operative in the BG here?",
    "All six schools agree on ekāgratā (one-pointedness) as the necessary mental condition, yet they differ on what the 'one point' is: Self, Brahman, Hari, Kṛṣṇa, ātman-distinct-from-Hari. Does the verse itself constrain the answer, or is the object of ekāgratā inserted by commentatorial projection?",
    "Śrīdhara equates viśuddhi with upaśānti (pacification) without doctrinal specificity — is this philological caution, bhakti universalism, or evidence that the verse's own semantic field is genuinely school-neutral?",
    "The verse prescribes a physical seat, a physical posture, and then mental control as a sequence: to what extent is the physical setup causally necessary in each school's theory, versus a conventional cultural frame that could be replaced without loss?"
  ],
  "everyday_applications": {
    "advaita": "Before meditation, deliberately clear the workspace — desk, phone notifications, ambient noise — not for comfort but as a physical enactment of sarvavikṣaya-upasaṃhāra (withdrawal from all objects). Treat this setup ritual as antaḥkaraṇa-śodhana (purification of the inner instrument): you are not relaxing, you are making the mind fit to inquire 'who am I?' The seat is the first act of philosophical seriousness.",
    "viśiṣṭādvaita": "Choose a corner of your home that you keep śuci (clean and consecrated) — a small altar, a clean mat, an image of Bhagavān — and return to the same spot daily. The physical purity of the place is not superstition: it conditions the mind toward avyākulatā (un-scattered-ness), and the image reminds you that you sit in the presence of the indwelling Lord whose support (āpāśraya) makes concentration possible at all.",
    "dvaita": "When sitting for japa (repetition of the divine name) or prayer, begin with an explicit acknowledgment that you cannot focus by your own power — ask Hari for the capacity to yoke attention. The Dvaita reading turns the instruction into a prayer before the practice: 'let me yoke' is a petition, not a command. This prevents the quiet pride of thinking meditation is a personal achievement.",
    "śuddhādvaita": "Do not wait until you have the perfect quiet time or the perfect āsana to begin smaraṇa (remembrance of Kṛṣṇa). Vallabha's 'satatam' (continuously) means that the yoking of attention to Kṛṣṇa is a background current running through all daily activity — cooking, walking, working. The formal seated session is a concentration of what is already present; it is not the only valid site of practice.",
    "bhakti": "Treat your morning sitting as pure abhyāsa (disciplined repetition): same time, same seat, same duration, same object of attention — without judging quality from session to session. Śrīdhara's equation of viśuddhi with upaśānti means the metric of success is quieting, not insight. If you rise from the seat slightly more settled than you sat down, the practice has done its work.",
    "advaita-bhakti": "When the mind wanders during meditation, Madhusūdana's model offers a specific corrective: notice which bhūmi (ground) the mind fell to — excited fantasy (rājasic), torpor (tāmasic), or restless sense-craving — name it, and consciously redirect toward a single brahma-ākāra vritti (thought-form shaped by the infinite). Using a Kṛṣṇa mantra or image as the anchor is not a concession to emotion; it is the sattva-dominant stream that Madhusūdana says carries the mind toward Brahman-sākṣātkāra."
  },
  "primary_meaning": "Seated on that āsana, make the mind one-pointed, rein in the activity of the senses and mind together, and practice yoga for the purification of the self."
