In simple words
Kanya is the Vedic name for the sign Virgo. It is ruled by Mercury and is dual (adaptable).
If your Moon was in Kanya, read "As your Moon sign". If Kanya was rising when you were born, read "As your lagna". Your chart page in Vedic mode shows both.
As your Moon sign
With the Moon in Kanya, your mind is analytical and your heart shows itself through helpfulness. You notice details, plan carefully and feel calmer when life is orderly. Worry can creep in when things feel out of control.
As your lagna (rising sign)
With Kanya rising, you come across as modest, intelligent and capable. Health, service and skilled work often shape your path. Being gentle with yourself balances your high standards.
Growing with Kanya
Write down what went well each day. Discernment includes noticing the good.
Vedic signs are measured from the stars (the sidereal zodiac), about 24° behind the Western ones. That is why many people's Vedic sign is one sign earlier than their Western sign.
