Knowledge of Atma is Adyatma. Advaita is Adyatma. Sage Sankara's Advaitic wisdom is pure spirituality or Adyathma.

Advaita is the nature of the Soul, the Self shines in its own awareness when wisdom dawns.

The Advaita is the Soul is the cause and the support of all that exists as the universe in which we exist.

The Advaita is present in the form of consciousness. Advaita is the root element of the universe. From the Advaita, the universe comes into existence. In the Advaita, the universe resides. And into the Advaita, the universe is dissolved. The Advaita is the parent of all that is there.

Religion is nothing to do with Advaita. Advaitic sect belongs to religion. Advaita is pure spirituality. The Advaitic sect is dualistic is nothing to do with the Advaitic truth which is hidden by the illusion. Mixing religion and spirituality is like mixing oil and water.

Religion is regarded as sacred and real by the common people, by the wise as false, and by the politicians as useful.

Religion and its sects are based on form, time, and space whereas Spirituality is based on the Atman the formless, timeless, and spaceless existence.

Religions hold birth, life, death, and the world as a reality. From the ultimate standpoint, the world in which we exist is an illusion created out of the Soul, which is present in the form of consciousness.

Advaitic sect holds the world (illusion) as a reality whereas the Sage Sankara says the universe as an illusion. Therefore, the individual experience of birth, life, death, rebirth, sin, karma, and personal gods and rituals belongs to the illusion. 

Thus Advaitic religious sect is a path meant for the ignorant populace, which is incapable of grasping the Advaitic wisdom hidden by the Maya or illusion. :~Santthosh Kumaar
