Mahima is one of the eight Hindu siddhis, or divine super powers, that may be attained by practices such as meditation or yoga. Mahima is the ability to expand the body to an infinitely large size, or the ability to become bigger than the universe.
The great sage, Patanjali, outlined five ways to obtain siddhis: birth, using herbs, incantations of mantra, self-discipline and samadhi.
Anima is one of the eight principal siddhis (abilities or magical powers) that are only attained through prolonged meditation and yogic practices. This particular ability is that of the yogi being able to reduce their size until they become tiny, to the point of being as small as an atom.
Siddhiis the term given for a spiritual or seemingly magical power or capability, which is obtained through rigorous and accomplished spiritual practices such as yoga and meditation. The Sanskrit word means “perfection,” “accomplishment” or “success” in English. It refers to the fact that siddhis are the fruit of the perfect achievement of spiritual practices.
Siddhis are generally powers to control the self, others and the natural world. It is said that, although they appear to be supernatural, they are actually accessible to all humans and can be explained in rational ways. They arise naturally when, through spiritual practices, the emptiness and openness of the mind is realized.
