Meeting with the hugging saint, Mata Amritanandamayi Devi, is referred as ‘Darshan.’ There is deep symbolism attached to the hugs and kisses. Darshan refers to Mata’s motherly embrace.
Mata herself spoke about the darshan
“Amma’s hugs and kisses should not be considered ordinary. When Amma embraces or kisses someone, it is a process of purification and inner healing. Amma is transmitting a part of her pure, vital energy into her children. It also allows them to experience, true unconditional love. When Amma holds someone, it can help to awaken the dormant spiritual energy within them, which will eventually take them to the ultimate goal of Self Realization.
