whenever I desire something in my mind or whenever a ray of hope or realization comes in my mind immediately I hear a deliberate negative mischievous voice saying 'NO' or anything negative which immediately dashes all my hopes and positivity.

Answer in Details

In the teachings and philosophy surrounding Lord Shiva, the experience of negative thoughts or intrusive voices is often understood as a part of the mind’s maya (illusion) and the play of dualities—hope and despair, creation and destruction. Lord Shiva, as the destroyer of ignorance and negativity, teaches us to transcend these dualities through self-awareness, meditation, and devotion.

Here are some guiding principles from Shiva’s path that may help you:

1. Practice Vairagya (Detachment):
Shiva teaches detachment from desires and outcomes. When negative thoughts arise, observe them without attachment or aversion. Recognize that such voices are not your true self, but fleeting clouds passing through the sky of your consciousness.

2. Meditation and Chanting:
Meditation, especially focusing on the mantra “Om Namah Shivaya,” helps purify the mind and quieten negative inner voices. Chanting this sacred mantra invokes Shiva’s energy, bringing inner peace and clarity.

3. Awareness of Ego and Maya:
Understand that the mind is influenced by ego (ahamkara) and illusion (maya). Shiva’s third eye symbolizes spiritual insight that burns away illusion. With regular self-inquiry (asking “Who am I?”), you begin to see negative thoughts as not your true essence.

4. Seek Shiva’s Blessings Through Surrender:
Pray to Lord Shiva with sincerity, asking for strength to overcome internal obstacles. Surrendering your struggles at Shiva’s feet can bring relief and renewed hope.

5. Rudraksha and Sacred Ash (Vibhuti):
Wearing rudraksha beads or applying vibhuti can be a symbolic and spiritual reminder of Shiva’s presence and protection, helping you ward off negativity.

6. Let Go and Trust the Cosmic Order:
Shiva teaches acceptance of the flow of life—creation, preservation, and destruction are all divine play (Leela). When hope is dashed, remember that even destruction is a step toward new creation.

Remember, Shiva resides in the heart of every seeker. When you face darkness within, invoke his grace, meditate on his formless nature, and trust that, just as night gives way to dawn, hope and positivity will return with perseverance and faith.
