lovely eyed.
'Ka' means Saraswati and 'ma' means 'lakshmi' hence lakshmi and Saraswati are her eyes.
Here we have to look at the two aspects of life,for that we have to know the nature of the two godesses,lakshmi and saraswathi.
The word 'Lakshmi' is derived from the Sanskrit word "Laksya", meaning 'aim' or 'goal', and she is the goddess of wealth and prosperity, both material and spiritual.Lakshmi is depicted as a beautiful woman of golden complexion, with four hands, sitting or standing on a full-bloomed lotus and holding a lotus bud, which stands for beauty, purity and fertility. Her four hands represent the four ends of human life:dharma or righteousness, "kama" or desires, "artha" or wealth, and "moksha" or liberation from the cycle of birth and death.Cascades of gold coins are seen flowing from her hands, suggesting that those who worship her gain wealth. She always wears gold embroidered red clothes. Red symbolizes activity and the golden lining indicates prosperity.
On the other hand we have saraswati the goddess of knowledge and arts, represents the free flow of wisdom and consciousness. She is the mother of the vedas.Goddess Saraswati endows human beings with the powers of speech, wisdom and learning. She has four hands representing four aspects of human personality in learning: mind, intellect, alertness and ego. She has sacred scriptures in one hand and a lotus – the symbol of true knowledge – in the second.With her other two hands she plays the music of love and life on a string instrument called the veena. She is dressed in white – the symbol of purity – and rides on a white swan – symbolizing Sattwa Guna or purity and discrimination.
So on one side we have lakshmi with the righteousness of dharma,and on the other we have the goddess who controls the aspects of true knowledge.Her she rightly depicts that one cannot be without the other.The two eyes do not see different things at the same time,so it is symbolically represented that even while acquiring wealth one cannot deviate from the path of seeking true knowledge and vice versa.It has to be done.That is the reason why during the period of samsara we seek for wealth and prosperity and at the same time we search for true knowlege.
You find the same meaning depicted in Soundarya lahiri thus:
"Savitribhir vacham Chasi-mani-sila-bhanga-rucibhir
Vasiny'adyabhis tvam saha janani samchintayati yah;
Sa karta kavyanam bhavati mahatam bhangi-rucibhih
Vacobhi vagdevi-vadana-kamal'amoda madhuraii."
Oh, mother holy,He who worships you,
Along with the goddess like Vasini,Who are the prime source of words,
And you who are having the great luster,Got by breaking the moon stone,
Becomes the author of great epics,Which shine like those written by great ones,
And which have the sweet scentOf the face of the goddess of knowledge.
