Steadfastness in sacrifice, austerity, and gift is also called 'Sat', and action in connection with these, or for the sake of the Supreme, is also called 'Sat'.

Swami Sivananda

And the steadfastness in sacrifice, austerity, and charity is spoken of as sat (good). And even the action meant for these is, indeed, called as sat.

Swami Gambirananda

Follows the commentary of Shankara (Advaita).

Devotion to sacrifice, austerity, and gifts is also referred to as Sat; and thus, any action for such purposes is known as Sat.

Swami Adidevananda

Follows the commentary of Ramanuja (Vishishtadvaita).

Steadfastness is performing sacrifice, austerity, and giving gifts; this act is hence justly called SAT.

Dr. S. Sankaranarayan

Follows the commentary of Abhinavagupta (Kashmir Shaivism).

Conviction in sacrifice, austerity, and giving is also called Sat. So too, an action done only for the Lord's sake.

Shri Purohit Swami

यज्ञ, तप और दानरूप क्रियामें जो स्थिति (निष्ठा) है, वह भी 'सत्' -- ऐसे कही जाती है और उस परमात्माके निमित्त किया जानेवाला कर्म भी 'सत्' -- ऐसा ही कहा जाता है।

Swami Ramsukhdas

यज्ञ, तप और दान में दृढ़ स्थिति भी सत् कही जाती है, और उस (परमात्मा) के लिए किया गया कर्म भी सत् ही कहलाता है।
