What's vShishya -

Well, you might have heard term "Guru" meaning virtuoso or maestro. Shishya (meaning dedicated student) is related term and often put together as guru-shishya parampara ("lineage") according to Indian culture. Guru is someone who has complete knowledge of the paricular field and shishya is someone who is trying to achieve all that advanced knowledge.

With technogy growing day by day, there is always something to learn new at every corner, I feel - I should always be in my student or shishya phase! As this is virtualization blog consisting more about VMware technology - I named it as "vShishya".
