Per Hindu practices, Meditation is the first, foremost step towards self realization. For attaining liberation and knowing god. It is a tool to calm the mind and prepare it for deeper states of realization (samadhi, nirvikalpa samadhi, etc). It is just a tool, like a hammer or chainsaw, that serves a greater purpose.
Yogic practices, at-least the physical ones, are for strengthening the body to face the rigors of long term meditation and deeper conditions.
Hindu scriptures clearly say that such practices are to be done under the guidance of a qualified guru (A true guru is one who has attained realization him/her self.)
Nowadays, business ventures are being built around this fad with mostly falsehoods mixed with grains of truth.
There is an excellent book [0] that records the conversations of one of the greatest modern era yogis [1], whose whole life was spent in meditation. The book is a great read and records his conversations with many western visitors. Do read it to get a better understanding of the context of meditation and related topics.
