What are some of the verses about life in the Bhagavad Gita which are applicable even today?

1) yada yada hi dharmasya galnir bhavati bharata abhyutthanam adharmasya tadatmanam srjamy aham Whenever and wherever a decline of righteousness and a predominance of unrighteousness prevails;at that time I manifest Myself personally, Odescendant of Bharata. 2) "vasamsi jirnani yatha vihaya navani grhnati naro ’parani tatha sarirani vihaya jirnany anyani samyati navani dehi" "Sri Krishna said: As a human being puts on new garments, giving up old ones, the soul similarly accepts new material bodies, giving up the old and useless ones." 3)"nainam chindanti shastrani nainam dahati pavakah na chainam kledayanty apo na sosayati marutah" "Sri Krishna said: The soul can never be cut to pieces by any weapon, nor burned by fire, nor moistened by water, nor withered by the wind." 4) Karmanye Vadhikaraste, Ma phaleshou kada chana, Ma Karma Phala Hetur Bhur matey Sangostva Akarmani You have the right to perform your actions, but you are not entitled to the fruits of the actions. Do not let the fruit be the purpose of your actions, and therefore you won’t be attached to not doing your duty. 5) Whatever happened was good Whatever is happening is good Whatever will happen will also be good What of yours has gone to make you cry ? What did you bring with you that you have lost ? What did you create which is now destroyed ? What you have taken you have taken only from here. What was given was given only from here. What is yours today, was someone else's yesterday, will be someone else's tomorrow.           Change is the law of the the universe
