It is slowly being replaced with other less toxic solvents. typical laboratory use of hexanes is to extract oil and grease contaminants from water and soil for analysis. Since hexane cannot be easily deprotonated, it is used in the laboratory for reactions that involve very strong bases, such as the preparation of organolithiums.
Sahasrara is the Sanskrit name for the chakra located in the crown area of the skull. It is the seventh and highest of the seven primary chakras. It is usually represented by the color violet.
Saá¹sÄra in Buddhism is the beginning-less cycle of repeated birth, mundane existence and dying again. Samsara is considered to be dukkha, unsatisfactory and painful, perpetuated by desire and avidya, and the resulting karma. Rebirths occur in six realms of existence, namely three good realms and three evil realms. Samsara ends if a person attains nirvana, the blowing out of the desires and the gaining of true insight into impermanence and non-self reality.
