Aurobindo's Integral Yoga is a unique and comprehensive approach to spiritual evolution that combines elements from Eastern spirituality with the concept of evolution. In this system, the ultimate goal is not just personal enlightenment, but the evolution of humanity as a whole towards a higher consciousness. Therefore, the concept of enlightenment in Integral Yoga is viewed as a continuous and ongoing process, rather than a one-time achievement.

According to Aurobindo, enlightenment is not a state of being that can be attained by renouncing the world or through ascetic practices. Instead, it is a state of consciousness that can be achieved while living in the world and actively participating in it. This is known as the state of "divine life" or "supramental consciousness."

Integral Yoga sees enlightenment as a multidimensional process that involves the transformation of the individual at all levels – physical, emotional, mental, and spiritual. Aurobindo believed that the human being is a complex being with multiple layers of consciousness, and each of these layers needs to be awakened and integrated for true enlightenment to occur.

The first step towards enlightenment in Integral Yoga is the awakening of the spiritual consciousness, which is the innermost core of our being. This is achieved through practices such as meditation, self-inquiry, and surrender to a higher power. As the spiritual consciousness awakens, it brings a sense of unity and oneness with all beings and the universe.

The next step is the purification and transformation of the lower levels of consciousness – the physical, emotional, and mental. This is done through various yogic practices such as Hatha Yoga, Bhakti Yoga, Karma Yoga, and Jnana Yoga. These practices help to remove the limitations and impurities that hinder the full expression of the spiritual consciousness.

However, according to Aurobindo, true enlightenment is not just an individual achievement but a collective one. Therefore, the final stage of Integral Yoga involves the transformation of society and the world at large. This is achieved through the manifestation of the "supramental consciousness" in all aspects of human life, leading to a harmonious and enlightened society.

In conclusion, Aurobindo's Integral Yoga views enlightenment as a continuous and multidimensional process that involves the transformation of the individual and society towards a higher consciousness. It emphasizes the integration of all aspects of our being and the realization of our true spiritual nature.
