There is an extremely rare and ancient Indian Tantra which is said to enable you to visualize what you will be in your next life and have a glimpse of your next reincarnation. Though it is of no use to know about your next birth, I will nevertheless tell you about the procedure as laid out in this secret Tantra scripture.
The seeds of the Ankola Plant [Alangium Salvifolium] called Sage Leaf Alangium; have to be crushed to extract the Oil from them. Then it is to be poured as Oil into a lamp with hand made wick of cotton. Then after the lamp goes off after all the oil has burned, gather the soot on a Copper Plate. Then mix this soot with the Pure Ghee [Clarified Butter] of a Cow to prepare Kajal [Kohl]. This Kohl is to be applied to the eyes, like you normally do.
Then you have to go and look in a mirror. The Tantra says that you will see what you are going to become in your next life; the next reincarnation.
