Ashram sadhana day is the day when the sadhana is to make the ashram actnic. All the elements that hinder the flow of actinic force are removed, such as old junk, unclean surroundings and poorly planned elements of the immediate environment. Broken items are also repaired. The focus is on simplicity.
In our teachings we're both monistic and theistic. In the beliefs of Saivism the idea of the three worlds is the basis and key to understanding temple worship, theism. The inner worlds are there to help you. The essence of the soul is already the same as the essence of God Siva, monism. You just have to find it.
