Meaning : You have a right to perform your prescribed duties, but you are not entitled to the fruits of your actions. Mā karma-phala-hetur bhūr mā te sa ṅ go ’stvakarma ṇ i Karma ṇ y-evādhikāras te mā phale ṣ hu kadāchana

Again the eternal and immortal form of the soul has been emphasized here. In the same manner, the soul remains unchanged, when it discards its worn-out body and takes birth in a new body elsewhere. When cloths or garments become torn and useless after getting old, we discard them in favor of new ones, but in doing so we do not change ourselves. In this verse or shloka, Shree Krishna reiterates the concept of rebirth, comparing it to an everyday life activity. Meaning : As a person sheds worn-out garments and wears new ones, likewise, at the time of death, the soul casts off its worn-out body and enters a new one. Identify yourself as pure and peaceful eternal soul not as your materialistic physical body. Death is solely the destruction of the materialistic physical body. We all know that one day we are going to die. Be fearless and live the life at the fullest. The soul is birth less, eternal, immortal and ageless It is not destroyed when the body is destroyed. Meaning : The soul is neither born, nor does it ever die nor is it that having come to exist, It will ever cease to be. Nothing is of permanent nature in this world. Have patience, learn to tolerate them without being affected by them. Ups and downs, tough times and difficult situations will come and go away in life. Similarly, pain and pleasure are impermanent and will come and go away. Like whether changes with time, it come and go away. Winters and summers are temporary in nature. This shloka or verse from Bhagavad Gita communicates a very powerful and important message that nothing is permanent in this life. O descendent of Bharat, one must learn to tolerate them without being disturbed. These are non-permanent, and come and go like the winter and summer seasons. Meaning : O son of Kunti, the contact between the senses and the sense objects gives rise to fleeting perceptions of happiness and distress. Āgamāpāyino ’nityās tans-titikṣhasva bhārata Mātrā-sparśhās tu kaunteya śhītoṣhṇa-sukha-duḥkha-dāḥ Their eternal soul having neither birth or death, they should not be grieved for. Same is true for Arjuna and others kings too. He was there in present in the battle of Kurukshetra and will exist in the future also. Krishna says there was not any time in the past when he did not exist. This verse explains the non lasting existence of everyone (soul). And surely it is not that we all shall cease to exist after this.

Meaning : But certainly, there was not any time in the past when I did not exist nor you, nor these rulers of men.

Na chaiva na bhaviṣhyāmaḥ sarve vayamataḥ param Na tvevāhaṁ jātu nāsaṁ na tvaṁ neme janādhipāḥ Still, I am trying my best to summarize best shloka or verses from the holy book that takes us through the spiritual essence of the Bhagavad Gita in the most practical and systematic way. There are many verses in Bhagavad Gita which I really like, and it is not easy to pick just one.
