Venus (Shukra) is the planet of romance, physical attraction, luxury, and early maturity. The 1st house (Lagan) is the physical body and the mind.
When a child is born with Venus in the 1st house, they mature very quickly, both physically and emotionally. They are naturally highly attractive and drawn to romance, fashion, and the opposite sex from a very young age.
Dr. Sharma gives a strict warning to parents: "Keep an eye on them." Because of their intense romantic energy, these children are highly prone to falling into secret love affairs, distractions, or bad company during their teenage years. They need careful, friendly guidance, not strict suppression.
