SAMADHI MEANS............

                     In Hinduism, samādhi can also refer to videha mukti or the complete absorption of the individual consciousness in the self at the time of death - usually referred to as mahasamādhi

Samādhi is the main subject of the first part of the Yoga Sūtras called Samādhi-pada.

According to Vyāsa, a major figure in Hinduism and one of the traditional authors of the Mahābharata, "yoga is samādhi." This is generally interpreted to mean that samādhi is a state of complete control (samadhana) over the functions and distractions of consciousness.

SAMADHI OF GURUDEV

                         Samādhi is described in different ways within Hinduism such as the state of being aware of one’s existence without thinking, in a state of undifferentiated “beingness" or as an altered state of consciousness that is characterized by bliss (ānanda) and joy (sukha

                         In BhaktiThe Vaishnava Bhakti Schools of Yoga define samādhi as "complete absorption into the object of one's love (Krishna)." Rather than thinking of "nothing," true samādhi is said to be achieved only when one has pure, unmotivated love of God. Thus samādhi can be entered into through meditation on the personal form of God. Even while performing daily activities a practitioner can strive for full samādhi.

                          "Anyone who is thinking of Krishna always within himself, he is first-class yogi." If you want perfection in yoga system, don't be satisfied only by practicing a course of asana. You have to go further. Actually, the perfection of yoga system means when you are in samadhi, always thinking of the Visnu form of the Lord within your heart, without being disturbed... Controlling all the senses and the mind. You have to control the mind, control the senses, and concentrate everything on the form of Vishnu. That is called perfection of yoga"

                              "Meditation means to absorb your mind in the Supreme Personality of Godhead. That is meditation, real meditation. In all the standard scriptures and in yoga practice formula, the whole aim is to concentrate one's mind in the Supreme Personality of Godhead. That is called samadhi, samadhi, ecstasy. So that ecstasy is immediately brought by this chanting process. You begin chanting and hear for the few seconds or few minutes: you immediately become on the platform of ecstasy."

.                            Yogis are said to attain the final liberation or videha mukti after leaving their bodies at the time of death. It is at this time that the soul knows a complete and unbroken union with the divine, and, being free from the limitations of the body, merges effortlessly into the transcendent Self. Mahāsamādhi (literally great samādhi) is a term often used for this final absorption into the Self at death.
