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


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 or ethical 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 nontheist to attain enlightenment, without   religions or spiritual masters, as is the case with Rajini Menon.
