Chitra means bright, varied, or a picture. The word survives in everyday Hindi: chitra is a painting or an image. The symbol is a jewel, which is raw material that somebody cut, polished and set until it caught the light.
In Hindu mythology, Tvashtar is the divine craftsman who shapes forms and fashions the weapons of the gods. Later tradition largely merges him with Vishwakarma, the architect of the universe, who built the palaces of the devas and the city of Dwarka. Vishwakarma Puja, when engineers, mechanics and factory workers across India worship their tools, honours this same deity.
So Chitra is not simply the beautiful nakshatra. It is the star of construction. A jewel is admired for its surface and it exists because of cutting, pressure and skilled work. The question this star keeps asking is whether the structure underneath deserves the attention the surface gets.
Its shakti (the special power a nakshatra carries) is gathering merit through good work. What you build well accumulates, both as reputation and as something more durable than that.
The Hindu month of Chaitra is named after this nakshatra, and it opens the traditional new year. Ugadi, Gudi Padwa and Chaitra Navratri all fall in it. Chitra is known for design, architecture and visual flair, and its natives are usually the best dressed people in a room without appearing to have tried.
