For a beginner in the spiritual path, a Guru is necessary. To light a candle, you need a burning candle. Even so, an illumined soul alone can enlighten another soul. Some do meditation for some years independently. Later on, they actually feel the necessity of a Guru, They come across some obstacles in the way. They are unable to know how to obviate these impediments or stumbling blocks. Then they begin to search for a Master.
