Jai Sri Baba Lal ji,
Atman is eternal and omnipresent but due to the coverings of Maya that high potency illusion, its presence is not experienced except with mystics and evolved man with truth of realization,
God is omnipresent in the universe, and his presence can be realized through objects with truth of existence,
So is the truth of Atman in the body which can easily be realize through practice of relevant Yoga in quest with truth and the cause,
Blessings of Holy Saints make it easy for man,
Jai Sat Guru Baba Lal Dayal ji,
