Prospects of a Child in Your Kundli, Know How Strong Are They! Make the moon calm. Keep a fast on Monday and donate white clothes, milk, curd, silver, etc. on Monday. If Moon is a benefic planet for that Kundli then one should wear Moti Ratna or Two Mukhi Rudraksha. If there is an obstacle in getting a child due to Mars, then pacify Mars and chant the Beej Mantra of Mars.
