Pilgrimage - Dieties - Vedas Place in Tulsi

The nineteenth century scholar M. Williams recorded that 

Yanmoole sarva tirthaani yannagre sarva devataa
Yanmadhye sarva vedaascha Tulasi taam namaamyaham.

I bow down to the Tulasi,

1. In its (Tulsi) roots are contained all places of pilgrimage;
2. its centre contains all the deities and
3. its upper branches all the Vedas.

“Oh Narada, wherever Tulsi grows there is no misery. She is the holiest of the holy. Wherever the breeze blows her fragrance there is purity. Vishnu showers blessing on those who worship and grow Tulsi. Tulsi is sacred because

1. Brahma resides in the roots, 
2. Vishnu resides in the stems and leaves and 
3. Rudra resides in the flowering tops.” 

(Padmapurana (24.2) Lord Shiva tells the sage Narada of Tulsi’s power)
