What is the Advantage of being in Shamadhi Stage?

Samadhi is oneness with the object of meditation. There is no distinction between act of meditation and the object of meditation. Samadhi is of two kinds, with and without support of an object of meditation Samprajnata Samadhi, also called savikalpa samadhi and Sabija Samadhi,meditation with support of an object. Samprajata samadhi is associated with deliberation, reflection, bliss, and I-am-ness The first two, deliberation and reflection, form the basis of the various types of samapatti: Savitarka, "deliberative": The citta is concentrated upon a gross object of meditation, an object with a manifest appearance that is perceptible to our senses, such as a flame of a lamp, the tip of the nose, or the image of a deity.[citation needed] Conceptualization (vikalpa) still takes place, in the form of perception, the word and the knowledge of the object of meditation.When the deliberation is ended this is called nirvitaka samadhi. Savichara, "reflective": the citta is concentrated upon a subtle object of meditation, which is not percpetible to the senses, but arrived at through interference,such as the senses, the process of cognition, the mind, the I-am-ness, the chakras, the inner-breath (prana), the nadis, the intellect (buddhi). The stilling of reflection is called nirvichara samapatti. Sananda Samadhi, ananda, "bliss": this state emphasizes the still subtler state of bliss in meditation Sasmita: the citta is concentrated upon the sense or feeling if "I-am-ness". Asamprajnata Samadhi, also called Nirvikalpa Samadhi and Nirbija Samadhi: meditation without an object,which leads to knowledge of purusha or consciousness, the subtlest element. read less
