Glories of Tulsi Devi pg 55, from Patalakhanda
Lord Siva said My dear Narada muni, kindly listen how I will relate to you the wonserful glories of Tulasi Devi. One who hears Tulasi Devis glories will have all his sinful reactions , stored from many births, destroyed and very quickly attain the lotus feet of Sri Sri Radha Krsna.
The leaves flowers roots bark branches trunk and the shade of Tulasi Devi are all spiritual.
One whose dead body is burnt in a fire which has Tulasi wood as fuel will attain the spiritual world, even if he is the most sinful of sinful persons, and that person who lights up that fire will be freed from all sinful reactions.
One who at the time of death takes the name of Lord Krsna and is touching wood of Tulasi Devi will attain the spiritual world.
When the dead body is burnt even if one small piece of tulasi wood is put in the fire, then that person will attain the spiritual world. By the touch of tulasi all other wood is purified. When the messengers of Lord Visnu see a fire which has tulasi wood burning in it they immediately come and take that person whose body has been burnt to the spiritual world. The messengers of Yamaraja will not come to that place when tulasi wood is burning. That persons body which has been burnt by tulasi wood goes to the spiritual world and on his way all the demigods shower flowers on him. When Lord Visnu and Lord Siva see that person on his way to the spiritual world, they become very happy and bless him and Lord Krsna comes before him and taking his hand He takes him to His own abode.
One who happens to go to a place where tulasi wood has been burnt will become purified of all sinful reactions. That brahmin who is performing a fire sacrifice and places among the other wood tulasi wood, will get the results of one agnihotra yajna fire sacrifice for each grain offered in that fire.
One who offers Lord Krsna incense made of tulasi wood will get the result of one hundred fire sacrifices and of giving one hundred cows in charity.
One who cooks an offering for Lord Krsna on a fire which has tulasi wood in it, will attain the same benefit as one who gives in charity a hill of grains as large as Mt Meru, for each grain of such an offering to Lord Krsna.
One who lights up a lamp to be offered to Lord Krsna with a piece of tulasi wood will attain the same benefit as one who offers ten million lamps to Lord Krsna.
There is no one more dear to Lord Krsna than that person.
One who applies the paste of tulasi wood to the body of the Deity of Lord Krsna with devotion will always live close to Lord Krsna.
That person who puts mud from the base of tulasi devi on his body and worships the deity of Lord Krsna gets the results of one hundred days worship , each day.
One who offers tulasi manjari to Lord Krsna gets the benefit of offering all the varieties of flowers after which he goes to the abode of Lord Krsna.
One who sees or comes near a house or garden where the tulasi plant is present gets rid of all his previous sinful reactions, including that of killing a brahmin.
Lord Krsna happily resides in that house town or forest where tulasi devi is present.
That house where tulasi devi is present never falls on bad times and due to tulasi devis presence that place becomes more pure than all the holy places.
One who plants a tulasi tree near the temple of Lord Krsna he will attain the Krsnas abode.
Wherever the smell of tulasi devi is taken by the wind if purifies everyone who comes in contact with it.
In that house where the mud from the base of tulasi devi is kept all the demigods along with Lord Krsna will always reside.
Wherever the shade of tulasi devi falls is purified and is the best place for offering fire sacrifices.
FURTHER GLORIFICATION OF TULASI DEVI---SRISTHKHAND
Karikeya inquired: My dear father Lord Siva,which tree or plant is capable of giving love of God?
Lord Siva replied: my dear son of all trees and plants Tulasi devi is topmost She is all auspicious, the fulfiller of all desires completely pure most dear to Lord Krsna and the topmost devotee.
Long ago Lord Krsna for the welfare of all conditioned souls brought Vrndadevi in her form of a plant and planted her in this material world. Tulasi is the essence of all devotional activities. Without tulasi leaves, Lord Krsna does not like to accept flowers, foodstuffs, sandlalwood paste, In fact anything without tulasi leaves is not looked upon by Lord Krsna.
One who worships Lord Krsna daily with tulasi leaves attains the results of all kinds of austerities charities and fire sacrifices. In fact he does not have any other duties to perform and he has realized the essence of all scriptures.
Just as the Ganges river is purifying all who bathe in her so tulasi devi is purifying the three worlds.
It is not possible to describe the full benefit of offering tulasi manjaris to Lord Krsna. Lord Krsna along with all the other demigods, lives wherever there is tulasi devi. For this reason one should plant tulasi devi at ones home and offer worship daily. One who sits near tulasi devi and chants or recites prayers will attain the results much faster.
All forms of ghosts and demons run away from that place where tulasi devi is planted. And all kinds of sinful reactions are destroyed when one comes close to tulasi devi. One who makes a garden of tulasi plants gets the results of all charities and one hundred fire sacrifices.
One who puts into his mouth or on his head the tulasi leaves after they have been offered to Lord Krsna
attains the abode of Lord Krsna. In kali yuga one who worships, performs kirtan in front of, remembers, plants or keeps tulasi, burns up all his sinful reactions and attains Lord Krsnas abode very quickly.
One who preaches the glories ot tulasi devi and also practices what he preaches becomes very dear to Lord Krsna.
One who worships tulasi devi has already satisfied his guru, the brahmanas the demigods and all the holy places.
One who offers a tulasi leaf to Lord Krsna becomes a Vaisnava very quickly. What is the need of understanding all the scriptures for one who has offered the wood or leaves to tulasi devi to Lord Krsna, for he will never have to taste the milk from the breast of a mother again and will never take birth again.
One who has worshiped Lord Krsna with the leaves of tulasi devi has already released all his ancestors from this realm of birth and death.
My dear Kartikeya, I have told you many of the glories of tulasi devi. If I was to describe her glories for eternity I still would not be able to reach their conclusion.
One who remembers or tells others these glorifications of tulasi devi will never take birth again.
Tulasi amrita janmasi sada tvam kesava priya
kesavartham cinomi tvam varada bhava sobhane
tvadang sambhavai aniyam pujayami yatha harim
tatha kuru pavitrangi kalou mala vinashine
One who chants this mantra while picking tulasi leaves and then offers them to Lord Krsnas lotus feet the results of that offering is increased millions of times.
