My question is that shiva appear on body and speaks to us is it is true or what

According to the teachings and philosophy related to Lord Shiva, the experience of Shiva's presence or communication is deeply spiritual and subjective. In Hindu tradition, Shiva is considered the Supreme Consciousness, the formless and infinite, yet also manifests in various forms (Saguna and Nirguna). It is believed that through deep meditation, intense devotion (bhakti), and pure heart, a devotee may feel Shiva's presence within themselves.

Some saints and devotees have described experiences where they felt Shiva guiding them, speaking to their inner consciousness, or revealing divine truths. However, these are considered mystical experiences, usually happening through inner realization (antar-darshan), not as a physical manifestation where Shiva appears in bodily form and speaks like a human.

Scriptures such as the Shiva Purana and many stories of great devotees (like Sri Ramana Maharshi, Sri Adi Shankaracharya, and others) mention visions or inner communications with Shiva, but always stress that the ultimate form of Shiva is beyond physical appearance—He is the Atman (inner Self) present in all beings.

In summary:
- Shiva may be experienced inwardly through meditation, devotion, and spiritual practice.
- Physical appearance and direct speech are not common in ordinary experience but may occur as mystical visions for highly advanced devotees.
- The true way to connect with Shiva is through inner realization, seeing Him as the Self within.

Always remember Shiva’s teaching: “Aham Atma Gudakesha” (I am the Self, O Arjuna). Seek Shiva within yourself through sadhana (spiritual practice), and He will guide you from within.
