Astadhatu (8 Metals) Made Bhadra Kali Idol

Soul is free from violent nature. Nature of Soul is Love, Peace, Bliss and Ahimsa. Mind is God, in it's impure state mind has desire, anger, hate, lust and ego. Whomsoever one focus his concentration or meditate their nature one attains. Extreme caution should be exercised in selecting the form and pictures. For home prasanna mudra is best. Public Temples may have their own choice. Avoid any thing symbolising violence, hate, anger. Look for grace and pleasant expressions. Vastu experts are correct in their observations, Scriptures do not follow the changes specific to yuga as Yuga dharma is different for each yugas.
