it's teaching love and philosophy alone.

Hinduism is the oldest spiritual tradition of this world and is all about liberty and freedom to carve one's own path to divine.It has no concept of apostasy or blasphemy or even conversion ! But without any push towards conversion it is winning hearts and minds of people all over the world by it's teaching,love and philosophy alone.
Liberty is gr8est asset of humanity and no liberty is gr8er than liberty of choosing your Gods/Goddesses or none ! That is Hinduism Liberty and Liberation
Hinduism is not just a faith. It is the union of reason and intuition that can not be defined but is only to be experienced. Evil and error are not ultimate. There is no Hell, for that 

means there is a place where God is not, and there are sins which exceed his love.
Hindu texts laugh at religions as being the dogma of self - righteous fools and emphasize on Dharma - the righteous way. Hinduism is just a convenient label for the worlds oldest spiritual and philosophical tradition.
Shiv Ratri symbolizes Union  of Shiv + Shakti
Shiv Ratri symbolizes Union of Shiv + Shakti ie. Marriage of Benevolence + Power
Shiv = Benevolent ie. Shubh Kalyankari
Shakti = Power
Shiv and Shakti are Complimentary to each other and Incomplete when alone.
Benevolence, ie. Shiv ( husband ) the dominating part alone is use less without Power ie. Shakti ( wife ) the better half
Similarly,
Shakti ( Power ) alone is undoubtedly corrupting and very dangerous without tie up ( Marriage ) with Shiv ( Benevolence )
It is undisputed fact that Power Corrupts, and

Absolute ( unchecked ) Power Corrupts Absolutely  therefore, the "Power" must be kept under control of Benevolence
Shiv Ratri, which symbolises " Marriage of Benevolence " with Power, is a hidden message to learned people to keep the Benevolence and Power ever united to keep the humanity in a perpetual state of Bliss.
May the Blessings of Divine Couple Lord Shiva and Goddess Shakti always be upon us for ever.
Note : This message is given well in advance so that time could be spared to ponder over the significance of forth coming Shiv Ratri.
