Shri Meru Yantra
Anyone can perform Shri Chakra Puja without the yantra being charged or blessed. One can always charge through their soul power. However if you are expecting extreme positive results and divine wisdom one needs to perform with guidance from a realized spiritual master. Whenever we charge\blesses the Yantra with Tri Shakti Energies the Yantra holds intense spiritual energy thousands of times stronger in magnitude and frequency. Before an aspirant will be provided with charged\blessed Shri Yantra he\she will be initiated into Tri Vidhya practice.
Shri Meru Yantra Meditation is one of the fastest way to experience serenity, bliss (anada) and communion with The Supreme Divine Energy. It is a very unique way to establish and maintain connection to The Supreme Divine Energy.
