How it Goes...

道生一，一生二，二生三，三生萬物。

षड्ज, Ṣaḍja/Shadja/Sadja, is the 1st स्वर svara from the 7 स्वर svaras of Hindustani music & Carnatic music. षड्ज, Sadja is the long form of the syllable सा. For simplicity in uttering — while singing the syllable — Sadja is pronounced as Sa (notation - S). It is also written षड्ज in the Devanagri script.

षड् - 6, ज -जन्म Sad is 6, 'H' is giving birth (giving birth to the 6 notes)

षड्ज is 6 in मराठी, Marāṭhī

• 1 & 5 (Sa & Pa) are Pure (incorrupt, clean, accurate, immaculate, holy)
• They are 陽, शुद्ध (Shudd)
• Hence they are the Rulers (Governor & [Prime] Minister)

• 2, 3, 4 & 6 are Gentle (soft, subtle, supple, ductile, pliable, pliant)
• They are 陰, कोमल (Komal)
• Hence they are the Klan (Gens & Family)
