"Temple architecture; sacred building science"
Quick answer
Vastu is a Tamil name meaning 'Temple architecture; sacred building science'. Numerology number 2. Lucky colour: White. Lucky number: 2.
Vastu is a beautiful Tamil boy name — a two-syllable name that is easy to call out and pleasant to hear. The name means temple architecture; sacred building science.
The name starts with the letter V, which in Chaldean numerology carries its own energy as part of the name's overall vibration. The first letter is the "cornerstone" — it reveals how the person approaches new situations and the first impressions they make on the world.
In Chaldean numerology — the oldest and most accurate system of name numerology, originating in ancient Mesopotamia — Vastu vibrates at the number 2. This number reveals the hidden energy and destiny connected to the name.
Names starting with V are traditionally considered auspicious for babies born under Rohini Nakshatra, Mrigashira Nakshatra and Vishakha Nakshatra, which falls under Vrishabh (Taurus) Rashi.
Combining the Nakshatra's recommended syllable with Vastu's Chaldean number 2 gives a name that honours both the birth star and its numerology vibration.
Tamil names belong to one of the oldest surviving classical language traditions — Tamil literature dates back over 2,500 years. Names are drawn from Sangam poetry, the Thirukkural, the names of Tamil deities (Murugan, Amman, Karthikeyan), and nature imagery. Tamil naming reflects a deep reverence for the Dravidian cultural identity distinct from Sanskrit traditions, though many families blend both.
Naming tradition: The birth star (Jathakam) plays a central role in Tamil naming. The first syllable of the name is derived from the nakshatra of birth, then a meaningful Tamil or Sanskrit word is built around it.
