The chakras in the palms of the hands are often (incorrectly in my opinion) relegated to minor status. These chakras transmit healing energy and receive energetic information from the universe.

    The palm chakras are used to channel healing energies to yourself and others and to receive impressions of the energy of a room, person, situation, etc.  Activation and  awareness of These chakras makes a major difference in the quality of life. They can often be opened by intention. 

    Practice in becoming aware of the energy of the palm chakras is a good place to start if you are at all interested in energy work and spiritual healing, or in any of the psychic arts.

    Healing chakras may also activate in the fingertips and elsewhere in the body.

The chakra in the palms  of the hands are powerful sensors and channels for vibratory information and energy . many adhere to the convention that  the
left palm receives or senses energy and the right palm sends it out.  My experience is that both hands will send and sense energy. you can improve and focus these functions  by  using intention and by allowing the input and out flow.

The most common healing  use for the receiving function is to scan the aura or area  for hot spots and other information  it can also be used to "taste" the atmosphere for information about  the general environment  or a speaker or book or situation.

The sending function is used for sending  healing energy, clearing rooms, charging crystals and objects and as a channel for various energy functions and purposes such as for blessing, protection and thankfulness.

    While it is possible to raise and use your own personal energy for healing this can be draining.

    While it is indeed important to learn how to build up and raise the vibration of your personal "chi"  it is far more effective for healing work  to learn how to bring in spiritual energy and allow it to flow through you. Some of the ways of doing this such as Reiki, for example, are acquired by having attunements done to your aura that allow you to connect with and use specific healing energies.

    It is more common to call in  and invite the energy by forms of intent such as effective prayer and via your high self and Companion Angel or Directly from God or other manifestation of High spiritual LIGHT and consciousness.

    There are many different systems taught for using and directing healing energies . You are advised to simply make yourself a clear channel for the healing energy and allow it to flow through you with no direction on your part other that that the healing be for the highest good and seated in unconditional LOVE.  It is emphasized that in most cases it is very important to remain neutral as to specific outcomes rather than attempting to impose your personal will to direct a specific outcome of the treatment though I do state internally what the situation is thought to be and if pain relief is sought.

    It is also possible following your intuitive and higher guidance as to appropriateness to move and remove and direct energy with gentle intention pushing or pulling holding the energy still or allowing it to flow directing tight laser like beams of energy to remove stagnant energy in a body and to mend tears in the aura  for example. On the vibrational level the difference between sensing and sending is kind of like the difference between sucking and blowing. Not everyone does consciously sense vibrational energy. You can still use healing energy even if you do not feel or see it.
