Union with shakti

Sri Sadgurubhyoh Namah

VBT 69 :

Shakti sangama samkshubdha shaktyaavesha avasaanikam,

yat sukham brahmatattvasya tat sukham svaakyam uchyate

Translation :

The union with shakti creates excitement, and at the end absorbtion into shakti happens. The bliss of union which is of nature of brahman, is the bliss of Self.

Commentary :

The bliss experienced when kundalini shakti rises and reaches the top, and an absorbtion happens with shakti, is said to be of the nature of brahman. This bliss is coming from Self.
