To avenge Kauravas who imprisoned his father, Shakuni used his father's after- life power to continue to transmit his will. He urged Shakuni to play a game of dice in a deceitful way with his bone dice rolling and transmitting energy favorably in order to defeat Pandavas through such evil spiritual betting trick.
In the nearer past also Sai Baba of Shirdi has undertaken to benefit willing devotees through a similar medium but with an entirely holy intent. Men of intense spiritual energy through the ages had and do have a capabity to transmit it by their intent alone without any bone or such medium to the deserving and suffering... sometimes in reply to their prayers or thapas. One also hears about "Shakthi paathams"..
It is known/ believed that certain esoteric Mantras have power to instill peace to restless departed souls by certain invocations and others are also used in religious functions to purify and and bring in peace..
Are there Puranic references to exert influence by transmission(Tantric or otherwise) after a person's death or also when living by design/intention for whatever purpose?
( It is well known that Shakthi transfer is made to occur between spirited persons e.g., from Sri Ramakrishna to Vivekananda on two occasions.. however all this during their living periods.)
