Story-day is for cultural exploration, puraanas and
parables and finding out about leading lights in spiritual philosophy.
Swami Sivananda's life can be read HERE; no need to recycle what is already provided so well at a sister site. What is important to note, though, is how the parampara is working. As has been mentioned prior, lineage and authority - 'provenance', if you will - is important. It is the lack of adherence to parampara which leads to mischief-making and self-agrandizement amongst those who would mislead the needy and the poor and to 'fleece' the wealthy… a phenomenon which Balakrishnan Menon/Gurudev was determined to expose. Even if the intention is well meant from one who would call themselves 'guru', unless they are firmly rooted in such a parampara and not twisting it to meet perceived needs or to their own ends, there is risk to the seeker. A True Guru has only the interests of the student at heart and focuses ever and always on the key purpose in life - to attain moksha.
To
illustrate this, here is a short video with a recording from the 1950's of
Swami Sivananda (with written transcription to aid you) urging devotees on to
the primary purpose of Vedanta.
