Sudarshan Chakra Deeksha is an armor of security for the Sadhak. Sudarshan Chakra is a spinning, disc weapon, having 108 zigzagged edges used by the Hindu god Vishnu or Krishna.
The Sudarshana Chakra is typically depicted on the right rear hand of the four hands of Vishnu, who also holds a Shankha, a Gada, and the Padma.
In the Mahabharata, Krishna, recognized as Vishnu, uses it as a weapon. For example, he beheads Shishupala with the Sudarshana Chakra at the Rajasuya Yagna of Emperor Yudhishthira.
He also uses it during the 14th day of the Mahabharata War to puzzle Duryodhana by summoning Jayadratha in front of Arjuna by hiding the Sun with his chakra. In the end, the Kauravas get fooled and thus Arjuna avenges the death of his son.
The Sudarshana Chakra is generally portrayed on the right rear hand of the four hands of Vishnu, who also holds a Shankha, a Gada, and the Padma. This Sudarshan Chakra Deeksha mantra is practiced for being victorious in any work and for happiness.
Many Sudarshan Chakra Mantra sadhana can be performed after receiving this divine Deeksha.
