In plain words
The Saccidānanda that shines with sameness and oneness in every human being is one!
In this vast universe every human being has an equal right. All are members of one family! It is most necessary to live in harmony with forbearance and concord, to do service to society in unity, and so to attain the Śānti of the Ātma. In every country of the world there are good people and bad; rich and poor; learned and unlearned. There are also narrow-hearted people who, born on one soil and breathing one air, have fostered strife and developed differences. Every man born in this world who hopes to win a name as a good human being has to face many hardships and losses, much blame and many harsh words. But it is most necessary to take no account of these at all, to face them with self-confidence, to experience fullness, and to make one's humanness worthwhile. Neither the divine feeling nor divinity is beyond the human. It is man's very nature! In every human being the Saccidānanda that shines with sameness and oneness is one! But man, unable to recognise the oneness in the many, becomes narrow-hearted and cannot recognise the breadth of society. Not only the feeling of oneness: man has to follow the divine path that is called ‘a kindly heart towards all beings’. Along with the words ‘Ekātmasarvabhūtāntarātma’, we must take in the principle of Prema and the principle of Satya as well, and make life worthwhile. If you would see God, it is not in some temple or some shrine or some house of prayer.
The true temple of God is the temple of man's heart!
God, living and the embodiment of consciousness, is shining in the temple of every heart. ‘Deho devālaya prokto jīvo deva ssanātanaḥ’: the true temple of God, the temple of Satya, the temple in which He is to be realised, is the heart of man! But the man of today ruins his Manas, sullies his heart, makes impure the heart that is a holy altar, gives place to mean and petty feelings, and so makes his heart unclean.
