18 THE OCEAN OF STORY
NOTE 1. THE USE OF TURMERIC
Turmeric (Sanskrit : kunkuma) has been used in India as a substitute for
saffron and other yellow dyes from a very early period. In the first place the
very colour, resembling sunlight, was auspicious, and therefore considered
to possess protective powers. Consequently turmeric, as well as the colour
red, figures largely in marriage ceremonies, and, in fact, in all important
functions occurring in the life of a Hindu.
It would not be an exaggeration to say that the general auspiciousness
of reds and yellows is a direct outcome of sun-worship in one form or another
(cf. our expression, a "red-letter" day). The idea of festivity connected
with the colour yellow, through its association with the sun, has given it
an erotic significance. This is another reason why it is the chief colour at
weddings, and in any relations between the sexes. Dymock gives numerous
examples of this, both from Sanskrit and classical European literature (" On
the Use of Turmeric in Hindoo Ceremonial," Journ. Anth. Soc. Bombay, vol. ii,
1892, pp. 441-448). Apart from the custom of smearing the body with
turmeric at weddings, garments dyed, or only marked at the corners, with
the colour became lucky. It is also used in cases of expectant pregnancy.
Thus Mrs Stevenson tells us in Rites of the Twice-Born, p. 113, that the
expectant mother sits on a low stool in the centre of a red-besmeared square
of ground. No men are allowed to be present, and all the ladies sit round
her and sing songs, whilst the husband's sister smears turmeric and rice all
over the young wife's forehead.
It would be superfluous, if not impossible, to name all the occasions On
which turmeric is used. Owing to its cheapness and its auspiciousness it is in
evidence wherever good luck is required, and this applies to worship as well
as to all important personal happenings in everyday life.
The introduction of aniline dyes, by which glaring colours can be easily
and cheaply obtained, has superseded the use of turmeric to some extent, but
so many and varied are the uses of turmeric from medicine to curry-making
that it still plays a very important part in the life and ritual of the Hindu.
