The first one is “Silence” and second is “Unity,” both are needed. Silence helps in individual progress and Unity helps in collective progress.

Silence:

It’s not just talking less with mouth; it is inner composure and tranquility of thoughts and emotions, it comes when confusions and unnecessary conflicts of mind stops. Mind has three types of thoughts: waste, negative and positive.

Thoughts are energies; waste thoughts have mix of harmful and productive energies. Negative thoughts have harmful energies and positive thoughts have productive energies. For inner silence both waste and negative thoughts are dangerous; where positive thoughts help first to replace with waste and negative thoughts and latter on becoming less and less toward silence.

Unity

Unity with gurus/masters, guides and the people of same interest – help to raise collective consciousness and spiritual progress. A human has social responsibilities along with his individual progress and it helps mainly to those people who are unconcerned to spiritual progress and living their life in pains & sufferings.
