Greatness of Shambhavi Mudra
शांभवी मुद्रिकाः कृत्वा आत्मप्रत्यक्षमानयेत।
बिन्दु ब्रह्ममयम दृष्टवा मनस्तत्र नियोजयेत॥
सत्यं सत्यं पुनः सत्यं सत्यामाह महेश्वरहः।
शांभवी यो विज्ञानियात्स च ब्रह्म न चान्यथा॥
~ घेरंड संहिता
By assuming the position of Shambhavi Mudra a Yogi should see the self. When
the Brahma (ब्रह्म) is seen in the form of a dot he should fix his mind on it
and nowhere else. A Yogi who knows the science of Shambhavi he himself becomes
Brahma (ब्रह्म) and none else. I, Lord Maheshwara (Shiva), am telling this again
and again that this is truth.
~ Gherand Samhita
Shambhavi Mudra is one of the highest practices of Kundalini Yoga. Shambhavi
literally means - pertaining to Lord Shiva. It has two fold meaning. Shambhavi
is also one of the names of Parvati. So Shambhavi means Parvati or Kundalini
Shakti. Another meaning is - assumed by Shambhu. So, Shambhavi Mudra is so
important that Lord Shiva himself sits in this mudra.
Shambhavi Mudra essentially involves fixing inner gaze (and in some
variations even the outer gaze) at Adnya Chakra. As the practice
matures you will see light and various visions at the eye brow center. The exact
visions and color of light may very from person to person and depends on several
factors. This "play of light" must be witnessed without flickering mind and by
maintaining outwardly and inwardly purity.
Although it is recommended to learn Shambhavi Mudra personally from an adapt
here is a technique of Shambhavi Mudra based on ancient texts.
