Instances of the dangerous use of them may be given as follows.

The King of the Panchalas killed the courtezan Madhavasena by means of the wedge during congress.
King Shatakarni Shatavahana of the Kuntalas deprived his great Queen Malayavati of her life by a pair of scissors, and Naradeva, whose hand was deformed, blinded a dancing girl by directing a piercing instrument in a wrong way.
There are also two verses on the subject as follows: "About these things there cannot be either enumeration or any definite rule.

Congress having once commenced, passion alone gives birth to all the acts of the parties." Such passionate actions and amorous gesticulations or movements, which arise on the spur of the moment, and during sexual intercourse, cannot be defined, and are as irregular as dreams.

A horse having once attained the fifth degree of motion goes on with blind speed, regardless of pits, ditches, and posts in his way; and in the same manner a loving pair become blind with passion in the heat of congress, and go on with great impetuosity, paying not the least regard to excess.

For this reason one who is well acquainted with the science of love, and knowing his own strength, as also the tenderness, impetuosity, and strength of the young woman, should act accordingly.
