Basis. (Glossary for the Vahinis)
The Lord is the Adhara, the basis, the support; the World is the adheya, the supported, the superimposed. The basis is in oneself, the nearest entity, the closest companion, the very breath and life of the individual. (SSS Vol.2, p. 167)
‘When you accept the five elements, you have to agree to the five-fold proliferation of each element, making in all 25 tattvas or principles. Only four elements, Earth, Water, Fire and Air are evident and perceptible; but Ether or Sky is the basis for all. So too, Manas, Buddhi, Chittam, Ahamkaram are all four cognised by experience; but the Antahkarana which is their base can only be inferred. All things of which we are aware are but manifestations of a Thing of which we are unaware. They derive their strength and support from the Unseen. That Unseen Basis of which you are unaware is I Myself, the Atma. All are based on Me.
That which is based is subject to change; growth, decline and modification. But the base or Adhara should not therefore be taken as subject to change. For example, consider the moon and its reflection in water. The image of the moon in the water is not steady; it shakes and quivers. It is the water that shakes and quivers, not the moon above. Ignorant people, who are like children, infer that the moon is itself shaking. The transference of the characteristics of the Adheya to the Adhara is the fundamental Asuric quality. The recognition of the eternality and truth of the Adhara even in the Adheya - that is the real daivi sampatti, God directed nature.’ (GV, p. 234)
