There is lot of difference between BEING ENGINEER(social reformer or mind reformer from "appearance or roopam" to "true-quality or satya -Gunam) and SAYING B.E., DEGREE HOLDER. So students and parents should avoid quackery of knowledge(courses) and believe in genetic inheritance of father's profession. If student believes in respecting father's profession,then how can he/she disregard his/her.genetic inheritance in choosing learning course ? Sociology says against quackery of mindset as it leads to conflict between BEING SO and SAYING SO. Bhagavadgita says against believing better para-dharma over believing better swa-dharma. From antisocial(ignorance)(crime)(immorality) comes social(knowledge). And from social(knowledge) comes political(voice) and adminstration(business solution). Hindu swamijis-babas should avoid perversion business and start believing in scientific temper on sociology and psychology both of which says about maximisation of lion-mindset or self-earning mindset and minimisation of tiger-mindset,serpent-mindset,dog-mindset and fox-mindset among humans.

Singing song/s is not voicing sentence/s BUT APPEARS AS SO.
And action by face,dance by legs and hands as well as body movements are not mindset BUT APPEARS AS SO.
