Touch is vital to well being because it allows a healthy movement of energy, in which you can release stagnant energy and add new energies to your physical and energy bodies.
In older traditions, cultures were much more friendly and embracing of the natural inclination to kiss, hug and be close to others.
When a person lacks touch, they become like a swamp that has stagnant energy, no vitality and no movement.
Touch must be held again in reverence as we evolve to be a more enlightened and connected species.
Nyasa is the Tantric ritual of placing divinity through the act of touch. In the Mahanirvana Tantra, sacred mantras as intoned as one touches and seals the psychic openings, moving from the top of the head, to the forehead, then eyes, ears, earlobes, nostrils, cheeks, lips, teeth, chin, neck, fingertips, palms, wrists, lower and upper arms, shoulders, chest, heart region, navel, thighs, ankles, insteps, toes and then finally the sexual organ.
By focusing on each specific part, one builds deeper awareness and excitement through the acknowledgment of divinity in detail.
