Chakras
Chakras are subtle energy points, literally called energy wheels. They function as places of energy exchange. In fact, we have hundreds of chakra points spread throughout our subtle energy system. However, the most well-known are the seven main chakras, which are connected in the central energy channel of our body, which runs along our spine. When the chakras function properly, these centres are gateways for vital life energy that enters our body through channels (nadis) and meridians through our subtle body. At the same time, they are also vanishing points for low-frequency energy to flow back to the subtle bodies that are being transformed. Each of the seven major chakras represents a level of consciousness or developmental stage of life, viewed from the perspective of our physical existence. Chakras may function less when they are in a negative state for a long time due to negative habits and accumulated emotions. This makes it difficult for the personality to fully integrate the level of consciousness that each chakra represents. When the chakras are open and in balance, they form an integrated system in which each chakra is dependent on the others for optimal function.
  

The string of beads is mainly used to count repeated mantras. So actually, it serves the same purpose as a rosary. Beads made of semi-precious stones, pearls, bodhi seeds or wood may serve all kinds of goals, like counting any kind of mantras, or other forms of prayer, bows, walk-rounds and such. The cord is the same for every mala, and should be made of nine threads, symbolising Buddha Vajradhara and the eight Bodhisattvas. The larger bead at the end stands for wisdom, realising emptiness, and the cylindrical bead on top of the large bead symbolises the void itself. Together, they symbolise the triumph over all adversities.

Mala 
A mala originally is a hinduistic and buddhist tool for prayer and meditation. It is used to count mantras during meditation. A mantra is a collection of words, often from Sanskrit, which is repeated several - traditionally 108 - times. While repeating, you focus on the meaning and vibration of the words, possibly combined with the accompanying visualisation. By training in a meditation practice like this, your thoughts come to rest and your body relaxes. Nowadays, a mala is also worn as a fashion accessory.

Why 108?
Malas have 108 beads because this number has great scientific significance in the Hindu and buddhist traditions.  The circumference of the sun times 108 is the distance between the sun and the Earth and the same is true for the moon and Earth.  Also, there are 108 nadis or energy channels in the body.  There are 54 sanskrit letters- both masculine and feminine, totaling 108.  There are 108 Puranas and 108 Upanishads.  The list goes on and on!!  So that same sacred number is used in malas.
