“The Matrimandir wants to be the symbol of the Divine’s answer to man’s aspiration for perfection. Union with the Divine manifesting in a progressive human unity.”
‘The Mother’
The Matrimandir and its twelve petals were completed after one year of excavation work, followed by 36 years of construction, on February 21, 2008.
However one project , the sliding Golden Doors for the four entrances, is still on-going. Also, in the meantime, the technical aspects of the heliostat are becoming obsolete and research is on-going to develop a state-of-the-art alternative.
When the Mother, in 1970, described her vision of the Inner Chamber, she spoke of a sunbeam, which would bathe the interior in a half-light. She stressed that “the important thing is the play of the sunbeam on the centre. Because that becomes a symbol – the symbol of the future realisation.” This beam is a ray of sun which is reflected down into the Chamber directly onto the central Crystal, by a heliostat whose computerised tracking system keeps it very precisely oriented. Electric spotlights create a similar effect at night and on cloudy days. The first heliostat was built in 1985 As one can see from the photos, the technical possibilities were quite limited at that time and it didn’t take too long before it had to be upgraded. The present heliostat has been in use since 2004 and both its mechanics and its computer system are becoming obsolete and unreliable, making maintenance increasingly difficult. As technology in the field of heliostats is moving very quickly, there are now newer generations of electronic and mechanical solutions available in India. The time has come to build Heliostat version 4.
For the new Heliostat, Matrimandir is working with IIT Madras (Indian Institute of Technology in Chennai). IIT Madras has proposed a completely new approach using a Solar Collector Tube.
This concept will replace the entire setup for sun tracking and eliminate the use of the mechanical moving parts in the existing mechanism. This concept uses a static fixture that collects the light and redirects it into a light beam by passing it through a tunnel and concentrating it by using lenses that always focus on a fixed point.
IIT is developing a prototype that will be tested on their premises before designing the final solution.
The budget for the study and the realisation of the prototype is Rs 5 lakhs.
The budget for the realisation of the final solution is
Rs 20 lakhs.

29 February 1956, During the common meditation on Wednesday
This evening the Divine Presence, concrete and material, was there present amongst you. I had a form of living gold, bigger than the universe, and I was facing a huge and massive golden door which separated the world from the Divine.
As I looked at the door, I knew and willed, in a single movement of consciousness, that “the time has come,” and lifting with both hands a mighty golden hammer I struck one blow, one single blow on the door and the door was shattered to pieces.
Then the supramental Light and Force and Consciousness rushed down upon earth in an uninterrupted flow.

The four Golden Doors are the last element of the Matrimandir that still have to be completed. There is a door in each of the Pillars. Once these curved door panels are operational, it will mark the completion of Roger’s design for the exterior of the Matrimandir.
These Golden Doors slide silently up from below the Matrimandir, emerging from between the top steps at the Pillars, to seal off the entrances.. Light weight, mounted on metal frames, they merge with the spherical shape of the Matrimandir as a whole and, when closed, complete the appearance of the golden sphere.
They are designed to be operated automatically, with sensors detecting when people are approaching. State of the art safety mechanisms are incorporated to ensure the full reliability of the system.
And now the time has come to make these doors work, in order to complete the Matrimandir. For this project, Matrimandir is working with IIT Madras (Indian Institute of Technology of Chennai). For the sensors, IIT Madras will use a system based on cameras to detect people; a system more efficient than conventional sensors. Each sliding door, moved by means of a ball screw, will disappear between the steps when opened. Sensors and cameras will detect people and prevent accidents. A safety study has been carried out, using the FMEA method (Failure Modes and Effects Analysis).
This project requires skills in mechanics, electronics and PLC programming (programmable logic controller)
Once the first Golden Door door is operational, the solution will be replicated for the other three.
The budget for the realisation of the 4 doors is
Rs 40 lakhs
