Lord Shiva is an embodiment of the four tattvas (principles). He is the pure, intense life energy. The Shiva linga – or the aroop roopa (formless form) of Shiva – signifies the tattva of responsibility and leadership in the formless form of Shiva. The Shiva linga has four parts – the base, which is like the frustum of a cone, represents the tattva of integrity. The part above that which is a mirror image of the base represents the tattva of authenticity. The baana or the column represents responsibility, and the yoni peetha or the gomukha from where the water falls off, represents enriching.
Worshiping Lord Shiva is nothing but connecting to His energy, which directly infuses the space of responsibility in the worshiper, and makes leadership happen in the person offering the worship. When someone worships Lord Shiva in the form of a Shiva linga in the Rudrabhishekam, they are connecting with divine energy of Lord Shiva, which will give the worshiper the clarity to resolve conflicts by taking responsibility and create life as he or she wants. Rudrabhishekam is one perfect way of taking control over situations in life and completing conflicts in life. Shiva linga is an embodiment of the whole, and human beings are parts of the whole. When someone connects with the Whole, any of the incompletions they may have get fulfilled because of the totality of the Whole.
