Maya and Bhagawan, are eternal, existing irrespective of the creation, maintenance or annihilation of the universe. Maya is not unreal because she is the potency of Bhagawan. The Lord is her master and she is the embodiment of His energy. Energy is always subservient to the energetic, just like a powerful person may not display his power although he does possess it.
The world that we see around is not really the way it appears to our senses. There is more to it than meets the eye. The reality of the world is covered by the power of Maya. This Maya makes the world appear and disappear. We as jeevas or living entities view creation which in itself is a setup of Maya and hence, there is a clout that covers the real picture present behind Maya. Our understanding is clouded by Maya. It will be interesting to understand how Maya creates the imagery that we are all used to which forces us into coming to the conclusion that what we see, hear, touch, smell and taste is real. The reality cannot be further than this.
The Gita needs to be revered at all times. It represents the vast expanse of all Vedic teachings condensed into 700 verses that have fathomed the length and breath of life, as a process. Many times, because of prior influence of other good scriptures, a person may tend to compare the Gita with them and may unknowingly misinterpret or miscalculate the deeper intentions of the Gita. It becomes vital for a man of intelligence to deliberate on the Gita more deeply, with a purified mind before jumping to conclusions.
Samskaras, are our mental impressions. These impressions dictate the quality of our life. Man is a machine in many ways. Our habits form tendencies and that automates us in many ways. Our habits dictate our lives and most times, our reactions depend on the habits that we have formed. Looking at the science of Samskaras can be an interesting journey towards understanding our own selves much better.
