In the Old Yogas, Yogins have confirmed to have Self Realisation or realization of Jivatma. But according to my understanding from Sri Aurobindo’s writings, Jivatma is the Vigyanamaya Purusha whose abode is Supermind. But since non of the realizations from Old Yogas had reached the Supramental Consciousness, then how we can say that they have realized the Jivatman which is also the goal of Vedantic realization🤔?

The origin of Jivatman is in the Supermind but a portion of it descends in the adventure of Time and Space as the psychic essence or the individual soul. It is like the Sun and its rays. The ray owes its origin in the sun. But to fulfil its destiny it travels far wandering through the universe. However far it may wander, it is always connected with the sun. The Jivatman that is realised by certain Yogis is the ray that has wandered upon the earth. It becomes the door to reach the Paramatama, that is the Sun..But before reaching the Supermind it comes across dazzling belts of Light, the Overmind, and mistakes it for the Sun itself.
