There is also a verse on this subject as follows:

`Men and women, being of the same nature, feel the same kind of pleasure, and therefore a man should marry such a woman as will love him ever afterwards.'

The pleasure of men and women being thus proved to be of the same kind, it follows that, in regard to time, there are nine kinds of sexual intercourse, in the same way as there are nine kinds, according to the force of passion.

There being thus nine kinds of union with regard to dimensions, force of passion, and time, respectively, by making combinations of them, innumerable kinds of union would be produced. Therefore in each particular kind of sexual union, men should use such means as they may think suitable for the occasion.⁴

At the first time of sexual union the passion of the male is intense, and his time is short, but in subsequent unions on the same day the reverse of this is the case. With the female, however, it is the contrary, for at the first time her passion is weak, and then her time long, but on subsequent occasions on the same day, her passion is intense and her time short, until her passion is satisfied.

Love acquired by continual habit
Love resulting from the imagination
Love resulting from belief
Love resulting from the perception of external objects

Love which is felt for things to which we are not habituated, and which proceeds entirely from ideas, is called love resulting from imagination, as for instance that love which some men and women and eunuchs feel for the Auparishtaka or mouth congress, and that which is felt by all for such things as embracing, kissing, etc., etc.

The love which is mutual on both sides, and proved to be true, when each looks upon the other as his or her very own, such is called love resulting from belief by the learned.

The love resulting from the perception of external objects is quite evident and well known to the world. because the pleasure which it affords is superior to the pleasure of the other kinds of love, which exists only for its sake.

What has been said in this chapter upon the subject of sexual union is sufficient for the learned; but for the edification of the ignorant, the same will now be treated of at length and in detail.
