Pooja rooms or Pooja enclosures or mantaps require simple and auspicious rangolis. There are some rangolis that are there for a long time (decades or centuries, I do not know) which are specifically meant for Pooja rooms, Tulsi plant (called Tulsi maadam) and Fridays.The following are some of the rangolis that belong to this category.
The design above is a deepam kolam that I regularly draw during Fridays. It is a simple rangoli with a number of parallel lines intersecting to form a deepam stand. Please watch the video for the method.
The next one is the famous Hridaya kamalam kolam considered to be one of the most auspicous rangolis. Hridyaya kamalam and the Hase above are considered to be Godess Lakshmi's favourite rangolis.
The next one is called the Kubera Kolam. This is a different type of Kuber kolam. The video below gives an idea as to how to draw it. This is not a common design but is used in our family quite often
The next rangoli is Aishwarya kolam a simple rangoli with dots. The pattern is 7 dots at the centre, 8 dots on either side, then one row of 7 dots on either side, one row of 6 dots on either side and finally three dots on either side
