Sadhana must be done in strict privacy
Sri Ramakrishna: "Meditate in your mind, in the forest, or in a quiet corner." The meaning of this is that all Sadhana must be done in strict privacy, that others may not come to know of it. If you steadily practise like this even for a little time, you will find what great joy and bliss will come to you. Swami Brahmananda in Spiritual Talks (1933), p. 227
