What simple worship of the Yantras can I perform on my own?
Yantras being living energy systems, they respond to all sensory stimuli. Traditionally a lighted oil-lamp (a small one!) in front of the Yantra was regarded as the best worship. Burning incense of various sorts is also well regarded as is the auditory stimuli of chanting mantras or playing tapes of sacred chants in the room. Perfume is perceived as a vain affectation and is to be avoided especially as most perfumes have synthetic components. Energy workers – Reiki, Pranic, Hands of Light, and so on – can beam at the Yantra to give thanks or worship and you will be stunned at the positive response you evoke.
