energy manipulation helps to control your energy and if mastered more energy can be put in a particular spell to make it strong ,plus doing spells or rituals etc on a full moon gives a boost .
There are many ways.
*Using herbs crystals days hours moon phases time and other correspondings of your Magick. Also practicing on regular basis gives experience and you grow strong. Knowledge is power and it increase creativity too.. Learn to work with meditation and energy work.

If I wanted to really power it up I would cast a circle specifically for drawing power on a full moon calling in the elements: Earth Air Fire and Water... Akasha. Use the five points of the pentagram. Use Crystals and Plants, set an altar and leap the fire. Its all very important along with visualization.
I would recommend chakra meditation. If you do this kind of meditation on a regular basis it will improve the connection of your energy and the effectiveness of the spells that you cast. Just look up chakra meditation on the internet and you should find it easily.
I know this is really late but here is a basic equation:
Energy input = energy output.
It is possible to cast spells without an incantation and without supplies but then you're relying only on your own core energies. This will drain you fast without making as much of an impact. If you learn to utilize meditation on what you want out of the spell beforehand, candles, diagrams, incantations, and other things then the more powerful your spell will be.
If you wish to increase the potency of your magic, then.I would suggest looking up and researching magical correspondences. For example, for spells that have to do with something creative or positive, cast them during the full moon. For spells that have to do with new beginnings, cleansing, and banishing, cast them under the new moon. Those are just two examples.
The air is saturated with energy released by the
breath of man and animals, just imagine a
spinning sphere drawing energy from the air
and into yourself.The kundalini at the bottom of
the spine, just imagine energy coming up from
the bottom of the spine.Energy from sexual activity
just imagine a sexual feeling in the body.Or from
the ground, just stick a wand into the ground or
a hollow stick and imagine a trail of energy coming
up from the ground and into yourself.Moon light
is a source of energy, just feel it's energy as the light
hits you and absorb it into yourself.
