Regarding satpurush : (Satpurush sathe atmabuddhi)
In meditation, understanding the union of the soul and the Supreme Soul, fostering intimacy, Anadimukta Satpurush is essential. Once this glory is understood, it is imperative to connect with Satpurush by soul, cultivate unwavering love, and develop Atmabudhhi with Him. One cannot advance even a single step on this path without the inner rajipo (blessings) of such a Satpurush.
Satputush elucidated clear concept of karan satsang and knowledge of parbhav and gave me blessing/promise of having been kept in Murti definitely after my transformation into Anadimukta made by Lord Swaminarayan. Countless Anadimukta become chirpy while enjoying the bliss of Murti. One should have excessive trust in such blessing and the knowledge of parbhav.
Grace of Satpurush is compulsory along with study of meditation, because only His grace, transform the soul into Anadimukta and bestow enjoyment of bliss of luminous Murti, without which, only by spiritual endeavor enjoyment of bliss of Murti is impossible. Addition of grace to spiritual endeavor is a must. As such, during day-to-day life we should be needy of His pleasure and for that we should lead the life of His liking.
