Hello all,   Here is an insightful article on female enlightened master Rajini Menon attaining enlightenment just through adhering to virtuous conduct and behavior.   https://www.lifepositive.com/a-light-unto-herself/
      If you do right, irrespective of what the other does, it will slow down the mind. - Rajini Menon     Wholesome virtuous behavior progressively leads to the foremost.~ Buddha AN 10.1


Swami Satchidananda also states in this regard....

“When even one virtue becomes our nature, the mind becomes clean and tranquil. Then there is no need to practice meditation; we will automatically be meditating always.” - Swami Satchidananda


I would say this showcases the importance of virtues and virtuous conduct as taught in the world religions and secular humanism, and shows that they are not limited to mere conditioning or are abstract contrivances as nihilism and existentialism believes them to be.

Sound adherence to morals and ethical conduct can even enable an agnostic or non-theist to attain enlightenment, without religions or spiritual masters, as is the case with Rajini Menon.
