The goal of life is the attainment of final beatitude or Moksha. Moksha can be attained by constant meditation with a heart that is rendered pure and steady by selfless service, Japa, etc. Meditation is the only real royal road to the attainment of salvation. Meditation kills all pains, sufferings and sorrows.
Meditation destroys all causes of sorrow.
Meditation gives vision of unity. Meditation induces sense of oneness. Meditation is a balloon or an aeroplane that helps the aspirant to soar high into the realms of eternal bliss, everlasting peace and undying joy. Reality or Brahman can be realised by man. Many have attained Self-realisation.
