Before actually commencing a ritualistic worship it important to arrange the implements and other substances (Puja Samagri) that is part of ritualistic worship. It is appropriate to arrange them based the level of the five Cosmic elements from the viewpoint of the science of Spirituality. Such an arrangement balances and coordinates five cosmic elements that are active in the Universe helping the embodied soul to derive maximum benefit of the ‘with attribute and attributeless frequencies emitted by the Deity. This arrangement indicates the journey of the embodied soul from Maya to Brahman that is associated with the five Absolute. An important component of the first level is the Puja Thali. The arrangement of the substances in the Puja Thali is explained ahead.
‘In the Puja Thali place turmeric and vermilion to the right side and bukka, gulal and shendur (Black, pink and orange coloured powders used in ritualistic worship which attract the Deity’s Principle) to the left side of the embodied soul.
The perfume bottle, gandha , flowers, durva and patri should be placed at the forefront in the platter because the subtle frequencies of the Deities are activated by the fragrance particles in the perfume, gandha , flowers and also by the colour particles in the durva and patri.
The betel leaves, betel nut and dakshina are should be placed at the other end of the platter Puja Thali because they are an effective medium of transmission of frequencies of the Deities.
In the centre, place the all-encompassing akshatā. As akshatā becomes the central portion in the Puja Thali, the frequencies of the five superior Deities namely Shiva, Shri Durgadevi, Shriram, Shrikrushna and Ganapati are attracted to them and are then transmitted as per the requirement to the other components like vermilion, turmeric etc. placed around them in a circular manner.’
