In recent times, some sociologists and pseudo-psychiatrists have been unnecessarily exaggerating the importance of the sex element in marriage. It is true that in such a relationship, this is definitely an important factor; when dispairity on this count sets in marriage, life appears lacking luster and charm, and incessant friction between the couples causes undue strain on the relationship. Astrological judgment duly takes this factor into account without needing biochemical testing or clinical dissection. It is judged not only under the 'Yoni' koota agreement, but also by considering the placement- and disposition- of certain planets - chiefly Mars and Venus - in certain houses (mainly the 7th). It is interesting to note that the term 'Yoni' indicates 'intrinsic nature' (not sex). The pseudo-psychiatrists consider sex as 'the most important biological function' - which had been propagated by Sigmund Freud; but astrology considers it as a 'vital force capable of being directed through creative channels' - which is quite akin to the realization of illustrious Carl Yung.
