The Householder Yogis
In ancient times, yogis and spiritual masters used to retreat to the mountain caves and forests, and lived as renunciants. This was partly the reason why the holy path of Kriya Yoga (a scientific meditation path otherwise known as the “Holy Grail” in India, which has also been known by other names) was kept in the hands of an exclusive few whilst the technique and knowledge of its existence almost became lost to mankind.
