He should always celebrate such sacrifices and rites as are completed in a single day. When, however, from performance of the (ordinary) sacrifices of sacrificers, the Sacrifice in Self begins, then for liberation he should sacrifice his own self in the three fires. Without linding fault with his food he should take five or six mouthfuls, offering them duly to the five vital airs uttering Mantras of the Yajurveda.
साधरकांश्च यजेद् यज्ञानिष्टीश्चैवेह सर्वदा। यदैव याजिनां यज्ञादात्मनीज्या प्रवर्तते।॥ त्रींश्चैवाग्नीन् यजेत् सम्यगात्मन्येवात्ममोक्षणात्। प्राणेभ्यो यजुषः पञ्च षट् प्राश्नीयादकुत्सयन्॥
