"Those with the vision of eternity can see that the imperishable soul is transcendental, eternal, and beyond the modes of nature. Despite contact with the material body, O Arjuna, the soul neither does anything nor is entangled."

This Atman is praised as Paramatman. Here in this sloka, Paramatman does not denote the Lord, but the superior [param] Atman, that is Jeevatman. Ayam = this, paramatma = Jeevatman, sarira-stho'pi = in spite of being in this body, avyaya = everlasting or indestructible or unchanging. Anaditvan = without a beginning. That is Atman was never created any time; it is existing forever, without a beginning and end. Nirgunatvat = without the Three qualities of sattva, rajas and tamas. Nirgunam does not mean without any Gyana. It means those qualities sattva, rajas and tamas, which are considered as blemishes are not in Jeevatman. Na karoti = [absence of these qualities make Atman] actionless. Body only acts and Atman does not act. The body has all these three qualities sattva, rajas and tamas and so acts. Because from Prakriti, the body is made. Sattva, rajas and tamas qualities are inherent in Prakriti. Without these three qualities, we will be actionless. Sattva makes us acquire knowledge, rajas makes us work for earning and tamas makes us sleep, etc. Therefore, Atman without these qualities is actionless. Na lipyate = [Atman is] not affected by the body's nature. The body has no influence on Atman, in spite of residing in the body. The body has many components, like for example it is the product of intercourse of two [male and female] bodies, it is having three - vata [air], kapam and pittham [according to ayurveda], it is made of four - consuming by drinking, licking, chewing and swallowing, etc. But on the other hand, Atman is single and is always constant. By visiting Ghatikachalam, we can understand this principle.
