Mantra Yoga is an invocation or a mystical formula, which aids the person to release the self and attain bliss and ultimate fulfillment. The sounds in a Mantra generate unusual mystic power. Mantra produces a set of vibration in the surrounding atmosphere & its force depends on the attitude of the person and the intensity of concentration. Mantras are performed with faith, the results cannot be analyzed measured, weighed, seen, but are felt.
The source of Mantra is only felt. It should be performed with due faith and all rituals, and then it is fruitful. You must have complete faith in Mantra you are reciting and must know its meaning. Do the things as per prescribed methods. You will experience sensation and vibration during or at the end of Japa, this is a sufficient proof to believe.
Mantra requires faith, Japa, hard work and per laid dictums to realize the desired objects and vibrations. Each Mantra has a different use. The vibrations of sound create desired reactions within the body too.
Three ways to perform Mantra -
Upanasu Japa - Only lip movement is there while chanting.
Manasika Japa - The Japa only in the heart without any sound or lip movement.
Vachanika Japa - Recite action in a low, medium or high tone.
Laya Yoga is an ancient form of meditation, with concentration or energy centers or chakras.
Sage Gorakshanatha, an ancient sage of Nepal, and a disciple of Matsyendranath is the founder of Laya Yoga. There are five main energy centers in the spine and two in the head. Layayoga attempts to locate these energy centers and channelize them through meditation.
Laya essentially means to dissolve all karmic patterns or conditioning and merge into transcendental reality. It also means deep concentration and making an effoert to obliterate the ego, thereby rising to higher state of consciousness, called Turiya.
Laya Yoga involves techniques of medication that cause the energy or prana to move in certain ways, to awaken the Kundalini, the coiled up energy at the base of the spine. Laya yoga channelizes the energy forces in the Kundalini instead of merely controlling mind. It is important that the Kundalini is activated through performance of Asanas, practice of Pranayama and making a conscious effort to guide this awakened energy in the spine and allowing it to immerse in the crown chakra.
The ultimate goal of Laya Yoga is to attain aupreme consciousness through Pranayama (breathe control); it is method to prevent to prevent fluctuations of the mind.
