I have already written about the Siththars' yantra. Generally these yantras are used for three purposes.
God is drawn on the yantras and giving power to it and blessings are recieved from that yantras by praying to it. These yantras are kept near the idol in the temple. These yantras are functionable only for certain time only.
In astrology to protect ourselves and the people around us from the effects caused by the planets, bad spirits we use these yantras. These are mostly used as remedies to protect from deficiencies.
The third type of yantras is very dangerous. These do not require any kind of pooja or any power need not be transferred to it. These will start functioning once they are drawn. The Siththars name them as vaagara chakras or siraga chakras.
The Siththars were so keen to ensure that these yantras are not known to the people. Hence the information of these chakras is mentioned in a hidden meaning. These yantras are shared only to the most trust worthy disciples.
In the next post I shall share some of the songs of Agathiyar and Pulipaani which speaks about the information related to the chakras.
