40.1 In the Samvat year 1876, in the early hours of Mahã sud 4 [19th January, 1820], Shreeji Mahãrãj was sitting on a decorated bedstead under the neem tree in front of the mandir of Shree Vãsudev-Nãrãyan in Dãdã Khãchar’s darbãr in Gadhadã. He was wearing a white khes and had covered Himself with a white chãdar. He had tied a white pãgh around His head, with a tassel of yellow flowers hanging from it. He was wearing a garland of yellow flowers around His neck. A sabhã of munis, as well as haribhaktas from various places, had gathered before Him.
40.2 Muktãnand Swãmi then asked Shreeji Mahãrãj, “What is savikalp samãdhi, and what is nirvikalp samãdhi?”
The previous Vachanamrut talks about SAvikalp and Nirvikalp States of Samadhi. This Vachanamrut talks about NIrvikalp and Savikalp Samadhi. Samadhi is usually trance, but lord Swaminarayan understands the practicality of Kali-Yug, and often does not talk about the mystic Yoga, but he talks about the characteristics or conduct or understanding of a person in savikalp samadhi or Nirvikalp Samadhi.
40.3 Shreeji Mahãrãj answered, “If a person who has sthiti in the svarup of Bhagvãn does not have any impure desires, but does have some pure desires. For example, ‘I wish to become like Nãrad, the Sanakãdik and Shukji’, or ‘I wish to go to the ãshram of Nar-Nãrãyan and stay with the munis there to perform tap’, or ‘I wish to go to Shvet-Dvip and become like a mukta of Shvet-Dvip by performing tap’ – then such a person is said to be in savikalp samãdhi. On the other hand, a person who does not have such thoughts has attained the characteristics of Akshar– Brahm, and remains engaged only in the murti of Bhagvãn, is said to be in nirvikalp samãdhi.”
When one takes up satsang, most of his impure desires are suppressed, and only pure desires remain. But these pure desires are also a cause of birth and death. The desire to become pure, the desire to make a temple for God, the desire to complete some scripture or some work related to God, is also a desire, which leads to one;s birth and subsequent death associated with that birth. Hence it is a Samadhi, a trance because there are no impure desires, but savikalp because he has some desire, although good and related to God, but not of God, or for God.
Whereas Lord Swaminarayan emphasizes on being Brahmrup and doing bhakti of God, as he mentions in Shloka 116 of Shikshapatri
Nijatmanam Brahmarupan dehatraya vilakshanam
Vibhavya tena kartavya bhakti Krushnasya sarvada.
Becoming brahmarup and doing bhakti of God is Nirvikalp Samadhi, where no other desire remains, Just one desire to serve God the way he desires. One’s mind is constantly engaged in the Murti of God in such state. This is called Nirvikalp Samadhi, where one is constantly engaged in the Murti of God.
