Uddhava Gita: The final teachings of Krishna & The lesser known companion to Bhagavad-Gita

The Uddhava-Gita, which is embedded in the Bhagavata-Purana, mentions eighteen paranormal powers (siddhi) that are the product of sensory control, regulation of the life force (prana), and intense concentration upon the Divine. Eight of these powers are said to pertain to Krishna himself, i.e., the great powers of miniaturization, magnification, levitation, etc. The other ten powers are said to result from the yogin's perfection of the sattva or luminosity aspect of the human personality or mind. Lord Krishna, who instructs the sage Uddhava, captures the esoteric principle underlying these practices when he declares in stanza 10.26: "Whatever a person who is attached to Me contemplates with his higher mind (buddhi), with the lower mind (manas) being firmly yoked in Me, that he will attain." In other words, we become what we contemplate with sufficient intensity.
