The nine schools of Indian or Hindu philosophy are:
Samkya, Nyaya, Yoga, Vaisheshika, Purva Mimamsa, Vedantha (the Vedic school branching off into Advaita etc), Charvaka, Buddha, Jaina. The nine schools contain sub=schools within themselves.
Of the nine, Charvaka makes for interesting study. Charvakans deny everything that is not tangible and therefore for them, there are no five elements or Pancha bhoothas. They recognize only four and discount the sky because the sky cannot be felt by any of their sensory organs. Osho and similar preachers and their followers must belong to the school of Charvaka philosophy where physical pleasure overrides everything else. Bodily satisfaction, momentary satiation mean more to them, and their mortal body is their prime focus. This type of men and women live for physical gratification and hence they have addictions taking to the bottle generally. Sex addiction and substance abuse are widely prevalent among them. They justify their preoccupations just the way they argue that there are only four natural elements earth, water, air and fire but never the sky that they cannot touch and feel. The charvakas have no respect for boundaries and have no walls defining their boundaries either. Its free for all for them. Since the charvakas consider themselves beyond answering the questions on morality, they do not believe in Karma. Charvakas in short are Bhogis. Their entire lives get devoted to fulfillment of their physical cravings. For charvakas, not just morality, even ethics are an issue. Not always clean hands for them. They will not hesitate to grease palms if they have to move matters and they won’t mind if someone greases their palm to get things going.
So for Charvakas, nothing is sacred, nothing is sacrosanct and nothing is too personal or private. Typically, Karpu does not therefore apply to them. In colloquial terms, we call charvakas, loose characters (with loose morals and ethics). Interestingly, the charvakas can charm their way into your heart with fakeness. Charvakas may also be non believers. Needless to say the Charvakas sell their soul that they are not borne with, without a second thought.
Charvakas may exhibit the Rajas guna typically, being materialistic. Charvakas do not bother about collateral damages either in their pursuit of their physical pleasures. Supremely selfish.
How brilliantly Indian/Hindu philosophies study the human species for their weaknesses and strengths.
