A piece of marked open territory on earth becomes a purchased land and the space within supposedly belongs to him also. When walls are constructed in that open space, it takes the shape of a building, the windows are created for light and ventilation, the door for guarding the inside and also act as an entry and exit point, the lock on the door to protect the house and its inmates from burglary etc.
This transformation of an expanded open space becoming a house is contributed by the walls that limit the space, the windows to let limited light and air, the door that limits the entry and exit and the lock that decides the entry or exit. Altogether , it is a mini limited space to live and also it is the springboard to jump into the unlimited, the vast expanse.
This body resembling the limited space of constructed walls, the senses to the windows, the mind to the door and the lock to the intellect may probably help us to understand this house and its operations better. We do need this house to live, but to experience the richness of our own home, the source, the unlimited, one needs to move beyond all the limited faculties. In fact, one learns to appreciate the house much more, understands the importance of keeping the faculties free from dust and knows to make the best use of it too.
The open space has no door and hence no lock too. But, the main door, mind has a provision for the lock, the thoughts. The key to lock or unlock is the detached attachment with the thoughts that flow. As long as we exist in this body, this key is also equally essential to have the functioning go smooth. Knowing when to attach(lock), knowing when to detach(unlock) helps in the easy entry and exit.
Blessed are those who have the house to experience the home within! Let us be grateful to all the Great Masters...
