Hladini Shakti is the bliss giving potency associated with
Lord Krishna. It is essentially a Vaishnava concept. According to some school
of thought, Radha is the personification of Hladini Shakti.
Hladini is Ananda or bliss.
Hladini stands for that power of Bhagavan which renders possible all experiences of bliss, from the lowest to the highest. All such phenomenal situations of bliss, as well as the infinite and unconditional transcendent bliss of Bhagavata himself, become possible because of the Hladini power alone.
Because of the Hladini Shakti of Brahman, the universe is
full of joy and pleasure.
This shakti is used by the Supreme Truth to carry out
blissfulness in the world.
Whatever resources are required to preserve the universe is
expressed through Hladini Shakti.
Hladini is considered the highest Shakti of Bhagavan as it
subsumes within itself both the sandhini and samvit powers of God. It is so
because the occurrence of any blissful cognition logically implies the background
conditions of cognitive capacity, i.e., consciousness (chit) and ontological
reality (sat). Thus, even among the three essential powers of Bhagavan it is Hladini
Shakti that most comprehensively and essentially represents his nature. With
respect to Hladini shakti, all the other powers are God are but adjectives of
qualifications. Hladini represents the innermost nature of Bhagavata. This confirms
to the Upanishadic description of the Highest Reality as raso vai sah, or ‘It
is absolute bliss.’
