What is Rangoli made of?

Rangoli is a coarse powder obtained by pounding a cleavable and lustrous mineral (shirgola). In the Konkan region (near Maharashtra and Goa states in India) the husks of rice are burnt and the white ash obtained is used as rangoli.

How is Rangoli drawn?

A pinch of Rangoli powder is taken using the index finger and thumb. As the Rangoli is a coarse powder of special soft white stone, which can flow freely when slowly released from the fingers.

To make a Rangoli:

1. The surface is prepared by cleaning it thoroughly. The surface was smeared with cow dung or ocher, and after it dried, rangoli was drawn on it at specific locations. In the ancient times it was a practice to daily sweep and sprinkle every doorstep with cow dung and draw rangoli.
2. A design or auspicious symbols or signs are selected for drawing.
3. After the selection, the required numbers of points are created on the floor using the Rangoli.
4. Then these points are joined with the appropriate design shapes, lines, curves, etc.
5. Once the shapes are drawn the colors are filled in using the same technique described above. The colored Rangoli is made by mixing the Rangoli powder and the color powder together in the required quantity to make different shades and tints. Picture of the colors available in market shown below.

Spiritual significance of Rangoli

In Hindu Dharma, rangoli is drawn during every festival, auspicious occasion, religious rituals, etc. All the festivals, auspicious occasions, rituals, etc. are associated with one of Deity principles. During these days, the Divine principle of a specific Deity is present in the atmosphere in a larger proportion on the day of the respective festival or is attracted to the venue where religious rituals of that Deity are being performed. In order to attract maximum Deity principle, rangolis that attract and transmit respective Deity principle are drawn so that everyone derives spiritual benefits from it.

According to a Principle in Spirituality that ‘word, touch, taste, form, smell and their energy co-exist,’ even if a small variation is made in the form and colour of the rangoli, its vibrations change. The booklet ‘Sattvik Rangolis’ illustrates various sattvik designs of rangolis which attract and transmit various Deity Principles such as – Deity Ganesh, Deity Rama, Deity Krushna, et. al.

The main feature of sattvik rangoli is that due to transmittance of Deity Principle, the devotees get various anubhutis (spiritual experiences) of Shakti (Divine Energy), Bhav (spiritual emotion), Chaitanya (Divine Consciousness), Anand (Bliss) and Shanti (Serenity).
