WHOLE-SIGN RASHI BHAVA & BHAVAT BHAVAM GEOMETRYAstronomical Projection, Dig Bala & Derivative Harmonics of Tanu Bhava
In Parashari whole-sign projection (Rashi Tulya Bhava), the entire 30° 00' sign occupying position 1 from the Ascendant sign forms Tanu Bhava. In Sripati cuspal trigonometry, the Ascendant degree defines the mid-point (Bhava Madhya) of Tanu Bhava. On the cosmic anatomy of Kalapurusha, Tanu Bhava corresponds to 01 Mesha (Aries).
Under the derivative house principle (Bhavat Bhavam), counting 1 houses inclusively from Tanu Bhava reaches its secondary harmonic: First House (Tanu Bhava). Regarding directional potency and functional behavior in Tanu Bhava, classical texts state a clear rule: Budha (Mercury) and Guru (Jupiter) attain full 60-Virupa directional strength in Tanu Bhava.
