Drekkāṇa (D-3)

Drekkāṇa (द्रेष्काण, also written Drekkana or Dreshkana) — the D-3 chart — is the third of the sixteen classical Ṣoḍaśa- vargas described in Brihat Parāśara Horā Śāstra. The Drekkāṇa reads the sahaja (siblings, courage, short-term initiatives, self-effort) register of the native, deepening the reading of the 3rd-bhāva of the Rāśi-chart. The name drekkāṇa is classical Sanskrit for "third part" or "ten-degree division," naming the chart's computational structure directly. Classical astrology records a distinct Jaimini-drekkāṇa scheme that differs from the Parāśara scheme given here; BPHS is primary.

Classical grounding

Brihat Parāśara Horā Śāstra's Ṣoḍaśa-varga-adhyāya names the Drekkāṇa's computational rule and its classical sahaja-register signification; Bṛhat Jātaka of Varāhamihira chapter 8 names the same scheme with extended classical commentary. Phaladeepikā, Saravali, and Jaimini Sūtras treat the Drekkāṇa at length. Classical sources also give each drekkāṇa a named iconographic- deity form (the drekkāṇa-rūpa framework described extensively in Varāhamihira's Bṛhat Saṃhitā and in the Yavana-jātaka) used in specific horary applications — this is a separate classical framework from the basic D-3 computation.

Computational scheme

BPHS's division rule for D-3: each 30° rāśi is divided into three 10° parts, with rāśi-ownership assigned as follows — the first drekkāṇa (0°–10°) is the same rāśi; the second drekkāṇa (10°–20°) is the 5th rāśi from the same; the third drekkāṇa (20°–30°) is the 9th rāśi from the same. The three drekkāṇas of any rāśi therefore correspond to the rāśi itself and the two rāśis that form the trikoṇa (trine) from it. Example: Meṣa's three drekkāṇas are Meṣa (0°–10°), Siṃha (10°–20°), and Dhanu (20°–30°) — the fire-element trine. Every rāśi's drekkāṇa-set is the elemental trine of that rāśi.

Classical significations

The Drekkāṇa-chart classically reads sahaja — siblings and the sibling-register (3rd-bhāva significations), the native's capacity for self-effort and courage, initiatives requiring personal energy, short-duration journeys, and the sibling-aspect of the lineage- register. Classical reading: the 3rd-bhāva of the D-3 chart reads siblings specifically; the Lagna of the D-3 reads the native's self-effort capacity; malefic placement in the D-3's 3rd or its trines modifies the sibling-register reading. The D-3 chart's reading is classically cross-referenced with the 3rd-bhāva of the Rāśi-chart and with Mangala as the classical sahaja-kāraka.

Classical interpretation register

The classical interpretation register of the Drekkāṇa is sahaja- specific — the chart specialises the 3rd-bhāva reading of the Rāśi without replacing it. Classical commentators note that the D-3 reading is particularly valued for sibling-register analysis (number of siblings, their welfare, the native's relationship with them) and for the assessment of self-effort capacity. The vargottama condition in the D-3 (a graha in the same rāśi in D-1 and D-3 — which occurs only when the graha is in the first 10° of its rāśi) is classically a significant strength-register. The D-3 is included in the classical graded strength-schemes Sapta-varga onward. The separate drekkāṇa-rūpa iconographic framework (Varāhamihira's Bṛhat Saṃhitā's 36 named deity-forms for the 36 drekkāṇas) is a classical supplementary reading used in specific praśna contexts — not part of the base D-3 computation but classically associated with it.
