Two Parallel lines

One of my US friend, at the time of visiting India amazed  "How the People are drawing parallel lines with hands without a Scale "

Yes, the Rangoli, (Kolam in Tamil) is one of the Cultural symbol of our country. 

The kolam is drawn to welcome the Laksmi, the Goddess of Prosperity into the home. Its secondary purpose is to add aesthetic value to the Hindu home.

The kolam is usually done by women, as it was the responsibility of the lady to maintain her household. In India, girls are trained to create the kolam from as young as six.
                                                             Apart from training her to be a good housekeeper, kolam making also serves to fulfil physical, philosophical and spiritual aims. Physically, the woman has to bend at the waist and knees, stretching her hands, legs and upper torso out to draw the kolam. This stretches the woman's muscles and joints, especially so since the kolam is usually drawn at dawn. Philosophically, the bending of the body symbolises humility.
                                                        Spiritually, the artist has to silently concentrate on her creation, as if meditating. Moreover, it encourages creativity

The Kolam Powder

The kolam powder is prepared with the help of the rice flour. This is another most important fact. The rice flour is very helpful in becoming the food of the ants and the other insects that feed on the kolam powder. This is the reason why the ladies prepare the kolam powder with the help of the rice flour. The rice flour of the kolam powder can also be considered as the food for the ants and the other insects.

Hats of to Indian sisters.
