Dissolution (Wyl. sdu ba) is one of the concluding sections a sadhana. After having either sent back the wisdom deities (jnanasattva) to their pure field, or dissolved them into their representation if there are some where we are practising through a rabné or consecration practice, we need to dissolve the samayasattva the visualized form of the deity. It is possible to also dissolve the the indivisible jnanasattva and samayattva without requesting the wisdom deities to go back to where they came from. This aspect of the practice is unique to the Highest Yoga Tantra. Through this process we purify the tendency to grasp at the extraordinary deities as being ultimately real. Then we rearise as the deity to eliminate grasping at non-existence and to illustrate the continuous yoga of maintaining the awareness of the deity in all our activities.
