Ravana Samhita, is written the Asura King of Lanka, Ravana himself.
It is a compilation of secrets and rules revealed by Lord Siva himself to Ravana.
One day, Siva entered into the house of Ravana, and was surprised to find him sleeping.
Ravana prostrated himself upon the floor in reverence.
With folded hands, he requested Siva to forgive him, as his offence was not a deliberate one.
Siva replied that the human birth was a difficult one to achieve, and it did no credit to Ravana’s intelligence to be daydreaming, especially during such a time.
Ravana requested Siva to be compassionate to his (obedient) servant, and to forgive the offence.
Ravana further asked Siva to order him as to which undesirable works he must shed.
Siva replied, my friend, things which are hidden even to the gods, those I shall reveal to you.
Pay attention to what I tell you. Whosoever shall accept what I have to say, he shall be freed from the burden of wrongdoing.
On hearing this secret dialogue, Ravana was lost deep in sorrow. Seeing him in a contemplative mood, and moved by compassion, Siva removed the affliction from his mind.
He said, this hidden secret was made manifest because of the baseness of your work. Whosoever shall accept (what I have revealed), it shall be of benefit to him.
Ravana replied, this boat (ark) – of moral guidance – shall help me cross the ocean of life. What capacity have I to sing its praise? Protect me; that is to say, instruct me further.
Then Siva understood that Ravana was his foremost officer, and instructed him:
On hearing this, Ravana praised Siva, and requested him to dispel his ignorance…
On hearing this, Ravana asked who will offer water to long-dead ancestors [a form of ritual or prayer to appease the spirits of the dead] if the man is without issue?
Replying to this, Siva said that if a man is without issue, a devoted (and chaste) wife may pour water to deceased ancestors.
On hearing this discourse, Ravana was lost deep in thought.
He said (to Siva): I have understood some of the things you have said, and other things I have understood not. How shall I gain salvation when my time comes?
Siva saw that Ravana was drowned in sorrow, and (out of his kindness) reassured him. He told Ravana not to think too much, but to be patient, and to meditate.
Because this discourse would free him from wrongdoing, and help him gain salvation.
Siva says : O Ravana! The person who is wrathful and displeased at the wealth or prosperity of others, that person will become a pauper in this world and will suffer in the other world.
Ravana asked Siva to give him some more advice…
Siva said that if a man does not follow his master’s orders, then he will be sorry for it.
On hearing this, Ravana questioned Siva saying what would happen if the man were given a task that were unreasonable or impossible to carry out?
Siva replied that until further orders are given, he should attempt to carry out that task to the best of his abilities.
Ravana asked Siva what if he failed in his duties altogether?
Siva replied that the man should ask for forgiveness (from the good lord) for his fault.
On the question of remarriage, Siva says that if a widower marries again, he will have neither happiness, wealth or progeny in this world.
Ravana replies that if a man without issue marries again, then he is not at fault. But, if he has a child (from a former marriage), he should not marry again.
Siva says : O Ravana! A person who keeps this discourse in mind, he will find happiness, both in this world and in the other world. And, he will carry out his duties to God with a selfless spirit and a happy frame of mind.
Ravana Samhita, has much more and few chapers dedicated to Astrology.
Ravana also invented the Ayurvedic method Arka Sastra.
Apart from that, upon his queen Mandorari’s request, he also wrote Kumara Tantra and Oddisa Tantra etc.
Kumara Tantra is a book with treatments for infant diseases.
In one of his writing, he writes “Eating beef cause to infect ninety eight new diseases to human beings.”
