Later, when the Mother left her body, she also went to that plane. What is exactly that plane where they are present now? Where in the Ashram literature or in the Agenda, the description of that plane can be found where they are present? Please elaborate.
Yes. The Mother and Sri Aurobindo have their permanent dwelling in the subtle physical plane. It is right behind the gross physical world (sthool jagat), similar in certain ways to the world we experience here but the forms there are far more beautiful and plastic. One can enter this world by Her Grace when there is an intense aspiration to see them. The Mother reveals this truth in some of her messages in CWM 13. It is described in some of her conversations on Auroville as well.
There is an elaborate description of the Ashram in the subtle physical world in the Mother’s Agenda. One can meet some of the sadhaks that have already departed such as Nolini da, Sahana di, Champaklal ji, Dyuman bhai, Nirod da. Its description can be found in some of Her conversations in The Mother’s Agenda, for example, after the departure of AB Purani ji. There is a lot of activity going on there to build the New Creation and its equipments.
You will find additional descriptions at places in Nolini da writings on the inner Ashram, Champaklal ji in Visions of Champaklal, Life of an extraordinary girl by Nirod da.
